Since we're talking about Twitter being a "protocol"...Is it likely they will be the only 140 character microblogging platform? What opinions do you have on Status.net and what they are doing with www.identi.ca? I think twitter has created a new protocol, but not a monopoly on that protocol. In 5 years people will be microblogging everywhere. That's what worries me about building something off twitter.
