if you want to get idea of what twitter is, where it is going (or if it is going anywhere) you should have look at this discussion on cnn (via @mashable/Pete Chashmore from mashable.com):
in my opinion they focussed too much on the chitchat, that is in fact being pubished through twitter. but I feel (as it was also briefly mentioned) it is much more about the fast exchange of informations between experts and of course between experts and people who want to learn about current issues.
those people who actively search for informations on twitter are not satisfied with the superficial and out-dated informations on plattforms like wikipedia (that’s my guess, didn’t do a survey on it or something). of course there’s google but you will never find the latest published article/blog post/… in the top 10 results on a specific topic with only one phrase.
Twitter offers a much faster supply of rich in content informations or at least tells you where to find it.
my hope is, that more people will find their way to twitter to share their knowledge or their sources of knowledge.
