Question regarding FB chat
3 points by Efasia on Feb 7, 2016 | hide | past | web | favorite | 2 comments
I have 2 friends at the top of my chat list. One I talk to every day. The other very rarely. When I was sick and lying around, I noticed that their on and offline times were almost identical. I noticed that this happened for many day. They are not friends. Is it possible that they are chatting/messaging each other?



I suspect that what you are seeing is an effect of Facebook pushing information to your screen <dom> intermittently rather than continuously. Because the flux architecture updates different parts of the screen independently, the section showing who is online can happen at a different rate than your main feed or notifications.


Thank you!
