His 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.
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 ;)
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.
