I know that while SxSW is going on, twitter is going to be useless. I plan to spend much of the next few days outside.

If you use Twitterific:

    defaults write com.iconfactory.Twitterrific tweetTextFilter -string "[sS][xX][sS][wW]|Austin"

On second thought, outside does sound nice. Nice weather here in the valley; not so much in Austin, I hear ;)

My mom asked me about Twitter the other day. That's how you know some technology or service is going mainstream.

Unless your parents are really technically savvy or something.

Twitter is absolutely mainstream now. It's quite weird - in the last several weeks almost all my friends and family have signed up. I'm not sure what the tipping point was, but celebrities appear to have a lot to do with it.

5 million users now -- I expect this to balloon exponentially very shortly.

Kevin and Alex from Diggnation were on Late Night with Jimmy Fallon a couple nights ago talking about twitter and doing an experiment. It's seeping into the mainstream very quickly, but it'll die out just as MySpace and Facebook are.

I can't remember the last time those guys predicted anything right...

Facebook's not dead; MySpace is still the top music web site on the planet.

MySpace may be dying slowly: I don't follow it enough to tell. Facebook is growing incredibly fast.
