Seconded. @tomraberbach, today in conversation someone mentioned Paul Buchheit's invention of Gmail as a 20% project. The next time, I'll mention you!

Heh I think the scale is a bit different, but I'm honored :)

It's not a typical day for me, but I sent 0 emails (Gmail is my standard) but edited 2 Docs with Markdown.

Well that's awesome!

Out of curiosity, do you mean the "autocomplete" feature or the import/export/copy/paste feature? (I did both)

Love it!
