Favoured Twit

I had to do some digging through google results and in several mashup directories before I discovered a mashup that didn't seem like a second rate version of an existing application or web site, or, an extra feature of an application I'm unfamiliar with. The mashup that caught my attention was Favrd, a daily Twitter best-of ("based on the number of times an item has been declared a favorite"). It's kind of compelling.
