I have at times been very popular and at other times been very definitely unpopular in the various congregations I have been in. It depends how you define "popular". JW's, like any large organization, are full of sub-groups. People of an alike nature tend to gravitate to each other.
When I was a child, my mother was a partier who got df'd for adultery. We had friends but we were not in the thick of the congregation. When my father re-married a pioneer, and became an elder, we were very popular as a family and invited to everything. I gave great talks, went out in service and was sometimes held up as an example to other youths. A few years later, I stopped going out in service, was a big flirt, and hated by most of the women in the congregation. Got df'd at 18. Big scandal. Lots of gossip. Jezebel type, like Brooke.
Three years later, reinstated, hung out with all the elder's and their wives, pioneered, very popular again. Flirted with one of the elder's, he flirted back, his wife got pissed off, gossiped and slandered me all over the hall. Bang, unpopular again. Had to move.
Then I had a baby, got busy trying to be the perfect JW family, husband made an MS. Now, we were popular, a good example to the hall. Ahhh! popular again! Then I got really bored, went to university, missed alot of meetings, got really sick, missed almost all the meetings and service too. What do you know? I am unpopular again(or more accurately, invisible).
So, I guess you could say "popularity" is very fluid and very dependent on who you are with and their perceptions of you. It has very little to do with reality and who you really are as a person. More to do with how you may be acting at the time and if the people you are in contact with are appreciative of that or judgemental.
Hope this helps with your armchair studies.
