Mostly, I just want to see what the difference is, compare the services, the features, and see which one works better for what I like to use it for.
While I love the ability it has to direct messages to a group, send small files and links, the fact that there is no mobile interface hurts. I use Twitter’s mobile interface with my Blackberry quite often to jot down a thought about something. Pownce not having one is a pretty severe limitation. Hopefully, as it develops further, there will be one.
If you’re interested in checking out Pownce, let me know I have a handful of invites.
