I've considered it, but I figure that the value of having it outweighs this. I don't see it as something that is strong enough to draw too many people away from the site. Maybe it'd be a good idea to remove it from the front page though to be safe. What do you think?

Removing it from the front page could certainly get you a few visitors who stay longer than to read that, react with "huh, guess this is not a classy site" or whatever, and leave.

For the record, I don't think it should be insulting that people care about appearance. I wish I didn't care about it, but I do (it isn't fair because it's not something you can control. however, pretending that you don't care is poor instrumental rationality). I get the sense that it's human nature, and you can't really help it. That's not to say that you think someone has some sort of lower "worth" if they aren't as attractive. It's just to say that more attractive people => better chances of finding a girl/boyfriend, and more fun hooking up. It has nothing to do with respect or social/intellectual interaction, just romantic/lustful.

Of course it's simply true that people are interested in the physical attractiveness of other people. Declaring that fact insulting is a nonsensical thing to do. It's the choice (not on this one isolated occasion, of course, but in the context of millions and millions of other such choices constantly made in the media etc) of the "hot" and "girls" framing of your understanding of this point that rankles, and may well rankle with others. Of course it's the women who are evaluated for their hotness, not the men. Of course hotness is chosen to evaluate them. Of course they're referred to using the term "girls". Because it's that way all the time. You'll tell me that it has to be like this, because that's how college-aged men speak and think. Pity you'll gain some people who speak and think like that and lose some who don't, in my opinion.

I've considered it, but I figure that the value of having it outweighs this. I don't see it as something that is strong enough to draw too many people away from the site.

I would caution you against the Typical Mind Fallacy and believing that other people will perceive writing the way you do.

In projects I've seen, the founders and marketing people worked on marketing copy, and spent a lot of time fine-tuning the messaging. As as programmer and a LW reader, it is unlikely that you are well-calibrated about marketing and messaging (similar to how the typical marketing person would be miscalibrated about web development). Getting feedback from others is important to avoid biases in this area.
