Facebook suggestions - how does it work?

[Jewelle]

I know this question has probably been asked a billion times before, but I'm just curious.

When I look at the "Find friends" page in Facebook I'm wondering how those people end up there. Some of them are obvious, such as people who share multiple friends with me, and people who went to the same schools, etc.

But, the top two people (who have been there for a few days) are confusing to me. The top one is the boyfriend of a male friend of mine. We only have two friends in common (I have over a dozen friends in common with other people on the list). I've been reading that if someone looks at your profile a lot it could push them up in your friend suggestions. Does this sound right? I'm wondering if he's scoping me out because he lives a couple of hours away from here, and maybe he's jealous that I hang out with his boyfriend a lot.

The second one on the list also only has two friends in common with me. This guy is a friend of my husband, and is an awesome photographer. His profile is open, so I've spent quite some time browsing the pictures in his profile because they are amazing. Does that mean that I've probably popped up on the top of his "find friends" list and he probably thinks I'm stalking him? lol Or, does that even count, and he has probably been looking at my profile too?
I'm not worried about my husband knowing that I've been looking at this guy's profile. We sat there and looked through these pictures together.
I'm not really worried about it at all. I'm just curious why two people are always at the top of the suggestions list, when the rest of the list changes constantly.
