Are you in a relationship with him on FB? It seems almost unanimous that people who report their significant other have them at #1, regardless of the level of interaction with them. I'm guessing that relationships and family members listed on Facebook are always at the top. Which makes sense intuitively if the endgame is predicting who FB thinks you will want to chat with.

Just checked and it updated immediately to "true" when I turned Chat Sounds back on and immediately to "false" when I subsequently unchecked the setting. So that at least leaves open the possibility that the ID number list updates automatically.

I've been keeping an eye on the sound thing and it has not changed. However, in hindsight I think I looked at the wrong section of code for what I thought I was looking for. In another section, there is this string:

"<li class="uiMenuItem uiMenuItemCheckbox uiSelectorOption" data-label="Chat Sounds"><a class="itemAnchor" role="menuitemcheckbox" tabindex="0" href="#" aria-checked="false">"

That corresponds to the setting Chat Sounds in the menu with the gear on the chat sidebar. Mine is turned off currently, but I will turn it on and refresh the page source to see if it changes.

IMO, it's not about about being related to chat messages or not related. It's definitely related. The #1 on my list has moved up to that spot recently, while our chatting has increased and interactions have decreased. There is some formula that we don't know and likely won't ever know. My guess would either be by what percentage of our messages/likes/interactions go to certain people or giving different actions relative weights (e.g. 50 chat messages = a post on someone's wall) and then that list is ranked according to some raw score.

I maintain, as I said below, that the users are assigned values from -1 to 1 with our various interactions factoring into that. The jackpot question people seem to want to answer is whether it's a one-sided statistic or two-sided.

Thought everyone might be interested in this - I did a little exploring (because it beats studying for exams). To the left of that list in the source code, there is a list called "privacyData" and after it is another string of user IDs, not coincidentally, all my friends (family members) I have blocked from chatting me or interacting. These ID numbers are listed as "13656xxxxx":-1, presumably assigning them a value of -1 each.

This suggests to me that the magic algorithm is assigning users a value from -1 to 1, with the more positive ones more likely to appear in chat. Between the privacy list and initial chat friends is this string of code: "ordered_list.available_target":0.85,"ordered_list.top_friends":5,"sidebar.min_friends":7"

This suggests to me that it's (1) searching for friends that have a value higher than .85, (2) always placing the top 5 friends from your initialchatfriendslist in your top half chat sidebar, and (3) always keeping at least 7 friends above the fold in the chat sidebar.

Finally, there's an input for "sound.enabled: true". Interestingly, after I turned chat sounds off, logged out and logged back in, it had not updated to "false" yet. This suggests to me that by monitoring when that flips, we can figure out how often the initialchatfriendslist is updated.
