Reading some email threads today, I saw mention of a domain I had never heard of before: start.com
Sure enough, it turns out this is a Microsoft-owned domain of some sort. What could be on it?

I started to search, and came across this blog post, which mentioned two cool URLs:
http://start.com/1/
http://start.com/2/

Cool! If you check out 1, be sure to click on the ‘show’ button on the left hand side to check out the toolbar.

Questions/comments? Submit feedback, there is a link on each of the sites.
Oh, and of course, they have a blog. :)
