Yes, I found this at TechCrunch and this thing is hot! I am going to have a lot of fun with this tool and i recommend you check it out. It is a next level vertical search and social bookmarking tool.
Out of all the great tools the first thing that struck me as totally new was its ability to auto tag sites that you have been to a given number of times. For those not interested in taking the time to leverage the power of del.icio.us, but want to take advantage of social bookmarking and the seeds of the semantic web, this may be for you.
