My response to Mr. Scoble is that I don’t think Twitter is the problem. Instead, his network might be the problem. If we get repetitive information from Twitter, we only have ourselves to blame. The problem is that if we don’t follow enough people from different types of networks, we’re always going to see the same information over and over.
No ad to show here.
Within this fundamental point also lies the best way to get the biggest benefit from Twitter. To explain why I say that, I’d like to dig into sociology theory a little bit, which I promise will lead to some practical implications in the end. First, a little background on Structural Hole Theory.
Ronald Burt’s theory of ‘structural holes’ is an important extension of social network theory, which argues that networks provide two types of benefits: information benefits and control benefits.
- Information benefits refer to who knows about relevant information and how fast they find out about it. Actors with strong networks will generally know more about relevant subjects, and they will also know about it faster. According to Burt (1992), “players with a network optimally structured to provide these benefits enjoy higher rates of return to their investments, because such players know about, and have a hand in, more rewarding opportunities”.
- Control benefits refer to the advantages of being an important player in a well-connected network. In a large network, central players have more bargaining power than other players, which also means that they can, to a large extent, control many of the information flows within the network.
Let’s continue to use Mr. Scoble as an example. I think it is safe to say that he has a high degree of control benefits — he is an extremely influential voice in the technology world, and with his 120 000 followers on Twitter he is clearly in a unique position to have control over certain conversations on the web. What he was complaining about was that he doesn’t always see the information benefits of Twitter, because he seems to be getting the same news over and over again. Fair point. So how can he fix that?
Well, Burt’s theory of structural holes aims to enhance both these benefits to their full potential. A structural hole is “a separation between non-redundant contacts” (Burt, 1992). The holes between non-redundant contacts provide opportunities that can enhance both the control benefits and the information benefits of networks.
The figure below shows a graphical representation of this definition.
The concept of non-redundant contacts is extremely important, and refers to contacts who give you access to networks you aren’t already part of. Now let’s look at how Mr. Scoble can increase the information benefits he gets from Twitter.
There are several ways to optimise structural holes in a network to ensure maximum information benefits:
- The size of the network. The size of a network determines the amount of information that is shared within the network. A person has a much better chance to receive timely, relevant information in a big network than in a small one. The size of the network is, however, not dependant merely on the number of actors in the network, but the number of non-redundant actors. In other words, it’s not just about how many people you follow on Twitter, it’s also who you follow. Pretty straight-forward, but let’s continue.
- Efficient networks. Efficiency in a network is concerned with maximising the number of non-redundant contacts in a network in order to maximise the number of structural holes per actor in the network. It is possible to eliminate redundant contacts by linking only with a primary actor in each redundant cluster. This saves time and effort that would normally have been spent on maintaining redundant contacts. What this basically means is that if you follow people who all follow each other, your network isn’t very efficient and you need to get rid of some people.
- Effective networks. Effectiveness in a network is concerned with “distinguishing primary from secondary contacts in order to focus resources on preserving primary contacts” (Burt, 1992:21). Building an effective network means building relationships with actors that lead to the maximum number of other secondary actors, while still being non-redundant. This means that if 10 people give you access to the same network of information, only follow the most important one — their voice will be clearer and not drowned out by the others.
- Weak ties. In his 1973 paper entitled “The strength of weak ties”, Mark Granovetter (Granovetter, 1973) developed his theory of weak ties. The theory states that because a person with strong ties in a network more or less knows what the other people in the network know (e.g. in close friendships or a board of directors), the effective spread of information relies on the weak ties between people in separate networks. “Weak ties are essential to the flow of information that integrates otherwise disconnected social clusters into a broader society” (Burt, 1992). This basically means that to get more out of Twitter, you need to figure out where your network is weak, and then follow those people who give you access to additional clusters. Building and maintaining weak ties over large structural holes enhances information benefits and creates even more efficient and effective networks.
So here’s the bottom line: to achieve networks rich in information benefits it is necessary to build large networks with non-redundant contacts and many weak ties over structural holes.
Some of these information benefits are:
- More contacts are included in the network, which implies that you have access to a larger volume of information.
- Non-redundant contacts ensure that this vast amount of information is diverse and independent.
- Linking with the primary actor in a cluster implies a connection with the central player in that cluster. This ensures that you will be one of the first people to be informed when new information becomes available.
If we apply these theories to Twitter, we quickly realise it is not the sheer number of “friends” in your network that count, it is the diversity of the people in your network that is most important. If you only have links to people in your immediate group of friends or colleagues, it will be difficult to get new information, since everyone will pretty much know the same things.
This is not to say that you have to start following all those random spammers on Twitter, but it does mean that people with who you have “weak ties” will often provide you with new information and therefore more benefits than your “strong ties”.
So here’s how to make sure you get the most out of Twitter:
- Identify the information networks you want to have access to (for me, it’s information about user experience design, product management, fatherhood, South Africa, non-profits, and music).
- Go through your following list and see where the overlap is — if there is a lot of re-tweeting going on of the same people, follow the person who gets re-tweeted the most. This will reduce your Twitter stream but still get you the information you need (and faster than before).
- Once you’ve reduced your following list, make your network as large as possible with the “weak ties” who will give you access to all the information you need. Again, look at who gets re-tweeted a lot, use Find2Follow to see if you are missing anyone in your network, etc.
I firmly believe that these theories show us that Mr. Scoble can reduce the number of people he follows while actually getting more information benefits from Twitter than he currently gets (I know he recently unfollowed a bunch of people, but he might be able to reduce and/or replace some of the people he follows with some “weak tie” follows). He will get new information faster, he will get it only once or twice, and the information he gets will be more diverse.
Now if I can just get him to follow me.
