It makes this look like Facebook Stalking Pro.
Just changing this stance to, "someone you find interesting" or better, "someone you might want to get to know better"-- leave the reason open-ended, because we all have different things we look for in people. As it stands, I'd never use the site because it sounds like your active userbase is full of people I wouldn't want to date.
Second, the wording is actually good as "cute/handsome". These are words that have a positive association with image without being sex-driven words, and aren't overly powerful towards seeming like a line.
Also keep in mind it's a mutual interest feature. Only once both people have listed each other as cute/handsome is a person notified, so it shouldn't result in negative behavior.
But you're right - there could be lots of reasons for interest other than attraction. Those can be individual features, like "There's someone who likes your taste in music" or "There's someone that wants to invite you to a FB event". The tool could probably be best served by allowing for a mix of these, so while Phil is attracted to Jackie's book smarts, Jackie is attracted to Phil's interest in social justice.
All points well taken and implemented. Please have a look at it, and provide another round of feedback if possible.
1. Get an editor to rework the copy and fix mistakes. There's a lot of phrases that are almost-but-not-quite correct, such as "safe friendly trust" (which is the first thing that people see)...You don't want people's mental spam-alerts to go off at first glance. A lot of the text is also awkward and slows down reading (avoid using the forward-slash...e.g. use "attractive" instead of "cute/handsome"
2. I didn't want to give access to FB to use the site so I don't know how it works other than the landing page...but is the only way to express interest is through calling someone "cute" or "handsome"? Other sites have used "I'm interested" as a way to express...well, interest.
3. Try to replace that stock photo with something unique when you can...and if you have to use a stock photo, don't use one of all white people, unless that's specifically the audience you're catering to.
4. Also, don't describe your users as "boys and girls" unless that's specifically the audience you're catering to.
5. Cut as many adjectives as you can out of the copy, it doesn't engender trust. Also, don't use the word "disciplined"...it doesn't have useful connotations in this context.
edit: After reading the About page, I have a couple more things to add:
6. There are so many reasons why people have negative feelings about traditional dating sites and you can't possibly enumerate all of them...so minimize the amount of telling people those reasons, as you make too many assumptions as is.
7. Related to that: there may be situations in which the phrase "call girls or prostitutes" is applicable, but the promotional copy for your positive online dating website is not one of them -- in any context.
