You might guess that I am a big fan of this idea - it's a kick starter project for micro-blogging and I am watching with interest.
Sometime this year - something has to happen with Twitter. If it goes away - then something needs to replace it. If it doesn't go away - it is still going to change.
Me - I have my Wordpress Blogs, Medium, Several Twitter Accounts and, and, and ... no Facebook - although I might even reverse that this year to grow my reach.
And of course, I have this platform that emanates from the mind of Dave Winer ...
So, with all of those places for me to provide content - not sure I have the capacity for another ... but we will see.
I just hope it is not another App.net.
