This morning I was trying to use Potlach to extend a street around a corner and end it in a cul-de-sac. I was able to get the street to curve around, but I couldn't really figure out how to make it end in a little neat circle like all the other streets around here. And I couldn't figure out the way splitting and joining. I had lots of problems with trying to move around, and also I got "stuck" in draw mode, so I would end up with road paths that went all over the place, then I had to go back and delete them. Maybe my mind is just too used to programs like Adobe Illustrator.

I might try some more editing later -- my first few impressions of it were just that it was too hard to use.
