That’s not entirely true. Twitter launched at SXSW, and people who were there can tell you that it was primarily used to build on the fly chat rooms during each session. Speakers would define the hash tag at the start, and then many would project the post stream up front and respond to questions or comments from the feed on stage. The audience would also discuss what was being said amongst themselves. It’s really just too big and too public for that to work anymore. It almost needs a feature where posting to a certain hashtag requires a password or being a certain user, then the 2 of them could’ve posted to that hashtag exclusively and been the only thing in the feed, and easily followed. Obvious problem there is that hashtags don’t really scale like that, but it gives you some sense for strategies they might take to tackle the issue.
