All of a Twitter

I'm really enjoying using Twitter wholeheartedly for the first time. It's a bit like tracking down an elusive party—a lot of my mates are hanging out there already. I'm also getting lots of inspiration for ideas for the integration of Blog Friends with Twitter (which is actually what prompted me to get Twittering). And you can now track my latest Tweets (should you really want to!) in the weaverluke sidebar.

But where's Twitter's business model? Fred Wilson, one of their investors, clearly feels that it would be a mistake to worry about that too soon, as it could distract them from growing their userbase as fast as possible. Nic Brisbourne agrees, but also points out that web entrepreneurs should at least have a "Plan A" for monetisation in their back pocket.

I suspect Jason Calacanis is right to point to mobile advertising as an attractive monetisation option for Twitter, but I'd go even further: maybe Twitter should get themselves acquired by a mobile telco who could pay for the SMS bills and integrate Tweets with mobile ads..?
