Some guy on YouTube asked me to tab out a solo, and I hate writing tab, so I told him I'd try to get around to it soon. He replied suggesting this site for doing tab. I'd never seen it before and thought it was really neat. Did the tab for him in a couple of minutes (it was only a couple of faster bits from one of my 1 minute long songs)
Took a little while to get some of the finer controls, but it's pretty good if you can live with the 6 string/21 frets only thing and slightly limited articulations.

That's pretty cool.
