Did you know Opera has widgets?

Here's a tip from Bob:
Okay, by now you should have SOME idea about what widgets are, or you know them as Gadgets. Anyway, you prolly didn't know that Opera supports them in-browser (you don't need anything else - like Vista or Yahoo Widgets Engine or Google Toolbar or any other toolbar/crutch). However, they didn't start out with a bunch, and it's a smaller developer base, so it taken a while until there was much of a selection or a single destination to browse them - that's THIS link
They've got lotsa cool stuff, useless stuff, useful stuff like security thingies and password generators ... you should check it out yourselves. It's one more reason to Switch To Opera, besides it being better, faster, safer, etc.
It's even got a couple sudoku games and that darned Badger Dance thing.
