fa-y-dar

My conclusion: Even if your  gaydar is not functioning properly, then don't worry. facebook could act in your favor.
You are straight. You have fb account. So won't you mention who you are interested in? Be honest here.

You won't respond to that if you gay though. Your conscience won't allow you to write interested in women but you can't write interested in men either. So solution is: you leave off the ticking job. That way you are in balance and having peace like Yin and Yan. I could be over generalizing here, but if you got friends who are gay and are open to you, check their profile they might have left the space.

Everytime i check someone's fb and do not see interested in information, my radar goes bleep and start analyzing many aspects i might not have thought before. Its not guaranteed that f-ay-dar works perfectly though, some might have little knowledge on how to work around on fb. But if someone is tech-savvy and his orientation is not mentioned, then that is of course a point to consider or sometimes explore as well. Who knows that person might be your Mr. or Ms. perfect :)

Update: After i made this prediction, i found majority not mentioning their interest. Hahaha has my predicament eaten mud before anyone points out fault in it lol :D
