Nik invited me to stumble. With my typical cynicism, I assumed it would be another community or something like that but I registered anyway. On the face of it, it looks a neat concept. You can track my stumbling at asuph.stumbleupon.com. The best thing is, with the stubmle toolbar, bookmarking becomes extremely easy! Plus, once you get your buddies (who are as crazy as you are) stubmling, I reckon it will be much more fun.
Time to stubmle?
