Rated 5 out of 5 stars
I use this toolbar for a lot more than what it is intended for. Since the toolbar can be auto-hidden with a button that comes with it, it tucks away nicely when it isn't being used to save screen real-estate. Because of that, I also store my live bookmarks on the same toolbar. I check all my blogs and then hide them away. I change the settings in the add-on settings to just show buttons so it looks more tidy. I'm not saying that I don't also use StumbleUpon for it's intended purpose. I love finding out about anything that I can.
Sometimes when sitting in art class, trying to overcome a brain-block, I resort to StumbleUpon for something to inspire me. When I can't think of anything better to do I just stumble. I love the chance to brighten my day or find something cool to share with my friends. StumbleUpon has brought me so much happiness!
