I’m experimenting with Pownce, on which I’ve had an account for some time but which is now taking off as a social application after public release a few days ago. So far it seems a lot like a “prettier” twitter with a few more features. I’ve been very impressed with the way you can import friends and contacts from Gmail, Facebook, Twitter, and many more applications. I still don’t like the fact that no productive person has enough time to really engage with any of these networks – thus the idea application would be one that would carry me around as I’m online rather than force me to log in and off and participate on the applications terms rather than mine. MyBlogLog still – for me – offers the best functionality of all of them and now with their new API I think it might be the best platform for our US History and Travel website where we are hoping to build something of a travel community from the many users who just drop in for a bit of info.
