Today is a big day for the Mac community. For one, 3rd-party developers are getting a huge open door to new markets they’ve never been able to reach before. Users will be getting a whole new window to discover software they never before knew about. Also, users are getting a simplified way to install and manage their applications.

10.6.6 is now available as a software update and with it comes the Mac App Store. It’s always a good idea to backup you Mac before installing major software updates, so you may want to do that now while you’ve got time (if you didn’t already backup last night).

I’ll be online all day today posting links and articles here, as well as thoughts on Twitter.
