A couple of years ago after seeing what a cool way Pownce had for adding your other sites/feeds, etc. I thought it would be a good idea to build a complete site around the concept. It would serve as one spot to be a pointer to everything/everyplace you are on the web.

I put together a mockup here http://syn.dicate.us/danhounshell/ and I started a proof of concept a couple of time, even as recently as a few weeks ago.

Alas, I was way too slow and someone beat me to it. And they did a good job, too. Really easy to create an account and add your links to Twitter, Facebook, etc. Cool stuff.
