As of 12 AM PST, Pownce, the Twitter-esque social messaging tool created by Kevin Rose, Daniel Burka and Leah Culver, leaves private beta and becomes open to the public. Pownce became open to a limited group of users in June of 2007 and has thus far amassed 150,000 users.

Although the developer has repeatedly claimed that Pownce is "not a Twitter clone," it is hard to look at the two services and not see the similarities. Both offer a way to send a message to a large group of people at the same time and have similar friend/follower structures.

The differences are that while Twitter can be highly integrated with mobile devices and SMS messaging, Pownce can only be used from the web site or the Adobe AIR client. However, Pownce allows user the ability to share files (up to 10 MB for free users, 100 MB for Premium users), invitations and set-up personalized groups. When Pownce goes live, it will also make it easy to import friends from services like Twitter, Facebook and Flickr.


Several of us here at DownloadSquad have been playing with Pownce on and off for quite some time, and while we think the service show considerable promise, Twitter still has our heart. The inability to use Pownce from an IM client or SMS outweigh the benefits of being able to share a file (we prefer e-mail or a link to a service like box.net anyway) or send out a group invitation. We do like the grouping feature and really wish that Twitter would implement somethign similar.

In the end, for us, it will all come down to what service our friends are using. As of right now, all of our friends are on Twitter; however, now that Pownce is open to the public, that could change. Check out Pownce and tell us what you think.
