Ladies and gentlemen, the doctor is in.

Crushes are an interesting thing. Part of what happens with crushes is you idealize the person of the crush. That is one reason why they happen. So it in fact makes lots of sense to have a crush on someone you don’t know well. You pick up on some aspect of them that is briefly present, and that strikes some chord. Maybe it’s their appearance or the way they speak relating to a parent or someone you already know (like handy said), or maybe it’s the tone and style that somehow reaches in to your person, and you feel like you know the person, like you are the person, that the two of you are bonded. It can be the fulfilling of an emotional need you didn’t know you had, or just touching the part of you that you hold most deep.
And generally they don’t last, because that is the nature of a crush. It isn’t real love, it’s built on your idealization of the person. Sometimes they can grow into something more, if you really get to know the person. Usually they disappear after some time, when you either realize they are going nowhere, or your idealization is shattered, either by seeing the picture, or meeting IRL, or they start posting more things you didn’t know about them and it diverges from your mental picture.
I go through crushes where for some reason I will become infatuated with a person - someone I know. For a while, I will think about her day and night, consistently returning to her. It will last a week to a couple months. And then one day it will stop, and I’ll move on, and have some other crush. That doesn’t make me fickle, it makes me human. Sure I’d love for those crushes to go somewhere sometimes, but usually there are reasons why they can’t.
As far as online crushes, I had a strong one with a woman I met through email. I’ve known her for 4 years now, we’ve met once IRL. For a while I had it bad, but now it’s more of a casual friendship. The fact that she’s 10 years older and lives 1000 miles away makes pursuing it daunting.
As for board crushes, I have a few. You can probably guess my big one, since it’s all over this board.
So evilbeth, you’re not a complete freak. At least for this. Unless we’re all complete freaks. 
And it will probably pass away eventually. Then you’ll find someone else to obsess over.

Falcon, does it “honk me off”? Only if I’m never on the receiving end of the flirting. As long as I’m getting my share, not really.
And now after writing all this, I see that ren popped in and said much the same thing. Oh well, I’m posting anyway.
