I recently went through the hassle of tracking down the necessary info to create a bunch of share buttons manually. Not hard, but time-consuming. This would have been very useful. Simple to use, too. Bookmarked for the next time I have to do that. Thanks!
If you're interested, there's a link to a blog post on the bottom of the website with code for some extra social networking/bookmarking sites -- if you'd perhaps like to add support for those. (I didn't add those to the generator because of missing icons in the icon sets.)
