Yep, this ! I stopped using StumbleUpon right after they decided to ditch the toolbar. The whole use case for StumbleUpon was to not visit a specific site but rather discover new ones. I used to absolutely love reading comments about the suggested pages as much as I liked the suggestions themselves. I also liked the tagging and searching through tags ..it was a bookmarking, social, reviewing, recommendation toolbar ...and then they went ahead and killed it trying to replicate arsebook or whatever.
