First off, Jim, thank you for all the work on this site for our enjoyment. It's the best site out there, and it just got better. Thank you very much.
Since you seem open to feedback on the logo, I will give you my unvarnished opinion. I was going to just email it to you but you seem to not mind the public comments...
For me, the logo is right on the edge of being very good, but fell over on the not so good side. It looks soft or feminine to me. What I'd prefer to see is a little more steely determination in the eyes, and a set mouth (just a line properly set would do) to emphasize that. I could find this logo to be very acceptable with a few tweaks. Right now it will have to grow on me.
Thanks again for everything.
