Originally proposed logo looks so much better than the accepted one. Perfect example of client interfering with suggestions that result in something safe but boring.
The logo for the accepted version is the best of the 3, in my opinion. However, when looking at it combined with the logotext it looks kind of odd in that the slashes are leaning away from the word curl so prominently. (#2 doesn't have this problem). No matter, though, it is a big improvement.

the important part of the name is URL after all. Logos are always tricky though; everyone wants to have input, which means you often end up with things like the last logo with lots of ideas mushed together.
