FF is becoming the Betamax to Twitter's VHS. Superior tech, more feature-rich, yet doomed to obsolescence/niche status as Twitter rides the wave of mass appeal.

Perhaps. But the cost-of-adoption model is different. There's little cost to switching, or using both.

I find myself paying more attention to FF than Twitter. FF not being in the spotlight may be a blessing.

Or maybe it's the Facebook to Twitter's MySpace?
