del.icio.us has gotten all the glory but furl was first and in many ways actually better. The downside is it’ so good that it’s more complicated to use which I suppose is why it’s not taken off like del.icio.us.

But web addict that I am, I use it, del.icio.us and Yahoo! MyWeb (bookmarking pages on all thress sites one after the other).

Furl is very good though, it’s just a bit more elaborate than del.icio.us (still my favorite).
