I've run into that twitter logo thing on summize.com (search.twitter.com) so many times. Every single time I'm there like a fool I click on the twitter logo, I never learn.

As a side note though, if you really want this article to be taken seriously (especially by people at twitter), I would rename it. I'm sure they see a million "why twitter will fail" style posts every day, so the honest points of your article doesn't shine through.
