What not to say on an online dating site: "Marry me!"

Yeah, yeah, I'm on an online dating site. I wish I could chalk it up as a mere social experiment (the idea of composing what is essentially, a dating resume, and what kind of attention your resume might elicit, and more importantly, from what kinds of folks, and how they, in turn, sell themselves, and so on and so forth). However, I did manage to put my pride aside and sincerely consider that communicating online is...well, valid. If friendships can be easily formed via common-interest words, why couldn't said relationship evolve into..hugs and kisses?
 
If it doesn't work out, it doesn't work out. I do not have my hopes up, and in fact, look forward to going on an awkward date where I take in my surroundings and may be forced to think that feigning diarrhea is the only possible way OUT.
 
I have not yet met anyone -- but I sure hope I have interesting stories to chronicle when I do, come the New Year.
