nice to see creole being compatible with org-mode tables and lists, mosts of my notes are in org-mode and i always wondered how to make everything markdown compatible; now i just switch to creole instead of being religious about markdown. good to see a ruby converter as well.
If github tables supported '+' as a field delimiter in the horizontal dividing line, in addition to '|' as they support currently, then github would support org-mode tables. It sounds like a small change. github, if you're listening -- any chance?
