#2Interesting hypothesis.

#3Interesting experiment. I had been wondering about this. I have also been thinking along the same lines as Florian about 'Find Friends'. I have certainly had some people appear there who I am aware of (e.g. neighbors) but we don't have any friends in common and they aren't in any of my email accounts.

#4Given that apps are banned from allowing people to know who visited their profile pages and facebook purposely doesn't have this functionality, it's interested that they use an algorithm that makes it possible for users to guess who has been visiting their profile page.

#5His tests don't seem to distinguish between H2 (recent visits by the friend) and H4 (recent interactions) very effectively. I could see H4 being a legitimate strategy but H2 is a bit more concerning.

"The selection includes many friends who you publicly interact with the most. Examples of public interactions include Wall posts, comments and mutually attended events. Facebook will never show friends based on whose profiles you choose to view or who you interact with over messages and chat."

#7This is wrong. My friend who passed away a month or so ago is constantly on my list.

Well, some people show up on mine with whom I've never interacted save making/accepting the initial friend request: this would seem to indicate that recent interactions weren't necessarily part of it.

I don't think that it does. The algorithm makes it possible for users to see who they publicly interact with the most, but this information could be gleaned by viewing that person's wall postings or photo comments. Therefore, the algorithm is just showing you people that visit your profile and interact, which you could figure out pretty easily anyways, not people who visit without leaving a mark.

Yeah, I think it's a mix of those two things - my list is composed of:
a) people I interacted a lot recently
b) people I interacted a lot in the past (and then almost not at all for a long time)
c) people I haven't really interacted at all
"c" must come from H2, "a" from H4 and that leaves "b" as either flaw in H4 or also a H2 - the latter would be a good news for me because people from that category are actually girls I gave up on a long time ago thinking they are not interested in me ;)
