I have a theory that one of the things that makes twitter appealing to many people is it's ephemeral nature. Seen this way it's historical flakiness is actually one of the the things that makes it popular. Whether valid or not, there is a sense in which twitter seems to be a good venue for casual social messages that aren't going to be archived and potentially used against you at some later date. Whereas facebook (again validly or not) sends a message that this is the repository of your accomplishments, and that it will be your permanent record.<p>The thing is that as human beings we need both fireproof digital libraries that can keep our memories safe, and the electronic equivalent of the floating world where the record of what was said evaporates with the morning dew.
I know exactly what the writer means by that problem. The first page is really useful to search for new tweets on a topic, but once you login to use what you found, you can't revisit the original home page without logging out.<p>I find that to be really annoying, especially when I want to tweet about multiple topics that I want to search for first.
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.<p>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.
