@fathom, I am with you there.
While I do have Twitter accounts connected to sites, I consider it mostly a notification system, and I definitely have yet to find any "incredible content" contained in ANY Tweet.
Maybe I have a tendency to be long-winded at times, but even when being at a middle ground, my usual attitude would be that any "thought" you can contain in 140 characters or less is not really worth wasting time on, let alone following. :)
But to each their own.
