Here’s the video, some notes, and some links from my recent talk about Twitter vs Pownce on the Lab with Leo TV show. I *really* shoulda included a review of Jaiku in my comparison. D’oh. *smacks head*
Twitter – multiplatform messaging system
founded by Evan Williams of Blogger and Odeo
-microblogging – super short, one thought, limited to one hundred forty characters
pros
-mobile ready – good for mobile. can use via sms. also works via instant messenger and skype
-everything gets a publicly available permalink – ie google can index it – and twitter has high page rank
cons
-one forty characters can be limiting tough to express complex thoughts
-good for sharing locations and ideas. not as good for sharing structered data like links and file and stuff
-only options are direct messages or public messages
-tough to find friends
-some spammers have already joined
-twitter goes down a lot
Pownce – multipurpose sharing system
launched by Kevin Rose, Daniel Burka, and Leah Culver
-similar to twitter but in addition to short blocks of text, you can also use it to send links, events, and files to friends
pros
-groups – sort your friends or contacts – can send direct, to a group, to all friends, to public
-threaded comments and responses to your post
-i’ve found lots of great music shared from friends on pownce
-nicer interface than twitter
-spam reporting built in
cons
-easy to ‘drown in the flow’
-lots of updates, haven’t found a great way to keep up with it all
-tough to find friends
