Microsoft Word and Open Office both lack one key ability, one you probably won’t notice until you stumble upon a situation when you need it. That ability is changing entire sentences or paragraphs typed in capital letters to lower case en masse.
(update: apparently Microsoft Office has an option to change the entire document in capital letters to lower case. It even does one better and changes it to sentence case. You just have to select text you want to change and then press Shift+F3)
Goformat.com, on the other hand, does have this online text formatting ability. This site isn’t an online word processor, nor does it aim to be. Instead, Goformat.com offers a number of ways to quickly format a block of text. Whether you want to transform all letters to upper or lower case, remove all instances of annoying characters such as “>” (which tends to show up in forwarded emails), or simply add a capital letter to the beginning of every sentence, Goformat.com can do the job quickly and easily.

Like the idea, but concerned about using a web app to edit text you want to keep secure? Don’t be. The site is built entirely using Javascript, and sends no data to any server anywhere.
While the text editing tools described above are what opens when you go to GoFormat.com, some other tools can be found by clicking the “Tools” link at the top of the page. These include a random password generator, a URL formatting tool, a tool that can reverse backwards text and a nifty timezone map.
