In terms of “gaming” twitter conversation tracking boards, I discovered the same thing when my students live-twittered the PR principles class. I know some people get annoyed, but that wouldn’t stop me. Next time I’d insert in the live stream tweets explaining what the hashtag means and where it’s coming from, so people know it’s not spam.

Personally, the part of your anecdote that I find the most interesting is that someone Tweeted you in order to tell you to move to a different communication medium. This implies that first and foremost, these services are not seen as all that similar by their regular users (assuming the Tweeter would self-identify as a ‘regular user’). And secondly, that there’s some kind of niche usage expectations which are being projected onto the different technologies. After all, why *not* use Twitter as a mobile media IRC type platform? There’s nothing preventing it. But yet, the dichotomy clearly existed enough for a ‘regular’ to get miffed.

I wonder who’s studying stuff like that about Tweeter and what that kind of stuff means. :)
