Today, I read a post on Twitter (via Abnormal Returns), the microblogging service that Fred Wilson, someone who really “gets” Web 2.0 is invested in and whose opinion I respect tremendously.  The post, which I will comment on briefly, made me think about Twitter and its use and application.

In the post, Om Malik, writes that Twitter faces a “scalability” issue.  I agree that it most definitely does, as there is tons of database space that is inefficiently used.  I believe that it can be solved if  1)  Twitter becomes profitable enough to justify such space, 2) Limits and/or Subscriptions are implemented, 3) A sophisticated and “smart” taxonomy is applied to “tweets”, and/or 4) Twitter evolves into “something else”.

Currently I think Twitter is at the edge of what will be embraced by the general public in regards to proactivity, necessity, and privacy.  Blogs have become pretty much mainstream, but only 7% of people blog and a little over half, 58%, regularly read them.  Blogging, like microblogging, is proactive.  Not many people are either motivated enough, have enough time, and/or are interested in writing a blog.  The same thing could be said for readers.
