Good list by Steve Rubel of Bookmarklets Every Blogger Should Have:
Here’s a bunch of bookmarklets that I use every day in Firefox. I highly recommend them. To use these, drag each one individually into your Favorites or Links toolbar (in IE), or your bookmarks folder/toolbar in Firefox
Good stuff. What I’d like to find is an extension to the toolbar in Firefox that let me add more bookmarklets (God, I hate that term. Anything ending in -let is ripe for extermination). Anything out there?
