I dont know how many of you know about this, but there is a program called SafariDockStatus that shows you the number of how many unread RSS feeds you have as a little red number on your Dock. Its the same way Mail shows you how many unread messages you have left. Its pretty cool. You can even change the size of the number and if you read the readme file, it will show you have to move the number around with some terminal work. Well just thought you'd like to know.
