To quickly describe what fonts the site currently uses --
verdana (smallest type)
arial (medium type)
courier (monospace & logs)
trebuchet (larger non-bold type)
arial black (logo and large bold type)
While I'm open to experiment with something like the liberation font family, Arial Black is and will continue to be the font for the BotB logo (with the kerning very low). I would very much like to have things looking the same across devices and OSes. Like most people, however, I hate changes like this to sites I visit regularly that have been the same for an extended period.
So, at the very least, I will be attaching Arial Black.ttf to the CSS to fix this issue very soon.
