The Font Thing is a piece of software that doesn't suck. Really, it's pretty indispensable. The Font Thing is a tool for viewing fonts, and runs on Windows 95/98/Me/NT/2000/XP. No word on whether it will be updated for Vista, or even whether it needs updated - it appears the developer (Sue Fisher) hasn't updated her website in several years.
I end up using this just about any time I need to choose a font for a project. It's got a fairly easy to understand interface, and allows viewing of multiple fonts with whatever sample text you choose, so if I'm trying to match a font on a graphic a client has provided and the graphic is too trashed to actually used, I can easily scroll through all the fonts on my system to choose the closest match.
The font info is also accessible through the app, so I can get information ranging from who owns the copyright on the font to the metrics, such as the smallest readable size and the average character width.
And the absolute bestest part of it? It's FREE. Not shareware or spyware or adware, it's FREE. And there's not even anyplace on the developer's website to indicate where to throw a few bucks in gratitude. Really odd.
