Looks like Twitter will be one of the first services to cross from Web2.0 onto mobile phones as well.
When you send Twitter a mobile text (SMS), it gets sent out to your group of friends and also saves to your Twitter page. Your friends might not have phone alerts turned on so they might check your web page instead. Likewise, you receive your friends mobile updates on your phone.
Twitter is a free service. At some point they may introduce optional, for-pay features or services but basic usage will remain free. Note: with phone alerts turned on.
Whilst I agree it sounds like a great application I can see it being bloody annoying, a sentiment echoed over at The Waving Cat!I think I’ll give it a miss for now!
