Finally got round to playing with Pownce even though I was given an account a couple of weeks back.
My first impression is that it’s a little similar to Twitter in terms of messaging except Pownce allows for you to upload files, links and events to your friends. You can also restrict who gets to see your messages and profile. Or you can just publish for everyone to see. You can also upgrade to a pro account for US$20 and this gives you the ability to send much bigger files and a wider variety of themes.
And if you want an invite, I’ve got 6 to give away. Just send me your name and email at isaak at isaakkwok dot com.
If you are already on Pownce, you can add me as a friend at http://pownce.com/isaakkwok
