StumbleUpon, Discovering Everything Rated 5 out of 5 stars
StumbleUpon, the only extension with tastes as eclectic as mine. I can find scientific updates, skateboarding photos, new hiphop and science fiction content, all with the same keyboard shortcut. Its ability to be as narrow or broad as you like is unparalleled, and there is always more to be discovered. It's like being a child with a ridiculously short attention span, stumbling through a forest with everything I love growing on trees. That metaphor got a bit out of hand but you know what I mean. StumbleUpon is brilliant, add it to Firefox now.This review is for a previous version of the add-on (4.11).
