I encountered this idea on X.com when someone linked to a personal website for a scientist who included a form for leaving feedback anonymously and at the time I didn't think much of it. Then over time the idea kept coming back to me and I eventually realized it was a brilliant thing to have. Let the people who know you (as well as strangers alike, but they've never been shy with feedback) have the opportunity to leave you honest criticism without feeling self conscious about it or feel like they are risking hurting your feelings. Or at least, if they do hurt your feelings then at least you won't know it came from them! So I decided to add one to my website. Go ahead, internet. Roast me. Or compliment me. I take those, too.
