Answer 1:
Well some people say that its who you interact with the most, but half of the people under my friends list, i havent done anything with them for like, months! facebook claims that its the people who you interact with the most but it could be that they dont want anyone to know about it. if it is who looks at your wall the most, then im happy that a certain someone has been looking at my profile;) well anyway, alot of people think that its who looks at your profile the most but others say that its who you interact with the most, and others say that its random and its different everytime you refresh it. but i refreshed it like alot of times and its still the same people! just in different order. i've done alot of research on this and my opinion is that its who looks at your profile the most. sorry if this is too long and i hope this helps you!
