Feedtagger.com has just been launched! Woo! I gotta say this is better than del.icio.us for me, helping me organise my life.
Using XMLHttpRequest makes it a fluid and fun experience... I can't wait to see what Tahpot will do, perhaps we'll see some bookmarketlets?
The other question: the profit model, will we be seeing some Google Profitwords soon? :P Let Tahpot know what you think and get your feature implemented soon!
