When you cut to the chase on this though, the question about Twitter has to be less about quantity and more about quality. As more and more of the mainstream begin to discover and possibly embrace Twitter (have you had any “I don’t get that Twitter thing at all” comments from people who are not like you?) the pure volume of visitors, users and tweets will continue to rise. What might not rise is the legitimate information that is in the cacophony of tweets. If it becomes harder and harder to mine and make sense of Twitter’s stream then it won’t matter how many people visit.
Twitter has done it’s part though by moving forward and making the overall experience more useful
Large sites like Twitter and Facebook before it tend to grow in step-like patterns, with bursts of growth followed by periods of flatness during which the site absorbs its new users and adapts to their needs. Twitter has certainly been improving the functionality of its own site, with the rollout of new features such as local trends, a better suggested user list, Twitter Lists, and the Retweet button. Maybe all that work is starting to pay off.
So how do you feel about Twitter today? I ask about today because the tide turns so rapidly in this space that even attempting to predict the future of anything is an exercise in futility. Obviously, no one has a crystal ball (except of course that broker who keeps calling you with “hot tips”) but to call how the social media landscape will play out over any extended period of time is a crap shoot at best.
