WOT
I’m a fan of Acronym Finder to look up unfamiliar acronyms when I’m reading a news story or what have you, but I didn’t like having to go to the site and type in the acronym every time I wanted to look something up. To save that extra second or two, I wrote a couple of browser buttons along the lines of Google’s. The Acronym buttons can be dragged to the appropriate Personal Toolbar or Links folder, depending on your browser, and when clicked will pop open a query window where you can type your acronym. You can also just highlight the acronym within the current page and then click it.
