I think it would be a great tool for the wind junkie community. It's a web based SMS text messaging app. It allows you to send updates or "tweets" to the twitter website via your cell phone, IM client, or a plethora of third party twitter clients. Your updates are displayed on your profile page and instantly delivered to other users (cell phone usually) that have signed up to receive your updates (known as followers).
So... imagine if everyone in the Lakawa community used twitter, and followed each other. When someone is heading out to the lake, or already at the lake, and sends out a tweet via their cell phone, the rest of his or her wind junkie friends would know whats happening. What gear are you riding? What's it blowin? Is it better at the Wac or WBL?
It'd be a bit more real time than this forum. Not that there is anything wrong with this forum

Anyway it's something I have been thinking about and thought I'd share.
