I read a post earlier this week explaining why the average person can't figure out Twitter, narrowing it down to:
* Following people who aren't interesting enough
* Following people who aren't creating enough value (as opposed to "individuals that can create the most engaging media")
* and that "Any individual who isn't "hyperconnected" is not going to benefit equally and I would argue is much more likely to eventually leave the site."
I don't outright disagree with these points ...
