Which picture should you put up for your myspace/etc main pic? IMHO, with all the "myspace angles", anyone can be seksy. Yes, even YOU. I think the main pic should be a closeup of your face, and I'm sure people will disagree with me... The reason I say it should be a closeup, is because in a browse/search situation, HB's will likely skim the profile pics. If you're a tiny spec in this tiny thumbnail, you are less likely to get click-through.
Now, you have 100's of pictures of you... How do you pick one? Which one looks the best? Fear not my friend! Sign up for www.hotornot.com and post your pics and have others rate your pic(s).
What I thought was hot (a pic of me with sunglasses) turned out to be the anti-hot. I took some pics and uploaded them one by one to HoN and eventually got my 8.6 rating up to a 9.7!! (btw, smiling will easily add 0.5 points! See all the cool stuff you're learning? Course you should know to smile by now.
)Now- be warned- their numerical system is fucked up. Don't pay attention to the main number. Even though it says I'm a 9.7, I'm not, trust me. Pay attention to the peak rating number. (I.e. the most people who rate you 5 or 6,7,8..etc.) Going by that metric, I'm a 7-8, slightly above average, heh. Always wait for at least 100 people, preferably 150+ to get a good statistical sample.
Good luck,
