Hey Adam and other Notae folks,
I just launched a new blog called Tagamac that focuses on tagging and Mac OS X software. Besides the fact that you might find it a useful (particularly for those who are new to tagging), I just wanted to say thanks for Notae; it’s one of the key programs that I’m using to run the site (I’m keeping my list of all the tagging software I know about in Notae).
If you check it out, please let me know what you like or don’t like! Since just launched it, I can still write or add just about anything. 
Hope it’s useful!
