Mary always adds great little tidbits to her blog posts and from following her latest entry on Learning 2.1, I've learned about a few other services in the Twitter vein. I’ve had a Twitter account for a few months now and although I don’t “twit” regularly, I have definitely experienced how this 140 character medium can come in handy.
Example: In Australia last month when I couldn’t get access to my email remotely to retrieve an address and send word to friend about my arrival time in Melbourne, I used Twitter to send a short message to her and 15 minutes later she sent a twit back (including her email). And at ALA, I used Twitter to connect with friends in both the exhibit hall and across the DC landscape. Since twits can be received via cell phones, it allows for easy communication and messaging with multiple friends.
Anyway, I need to look more into Pownce and others. I received a Pownce invite from someone (Mary was it you?) about two weeks ago, but now can’t seem to find it.
BTW: Twittervision 3D is just too entertaining. It makes me feel like I'm a member of the Space Shuttle.
