I came in via crosswords. The site offers an outlet to caring for an Alzheimers with whom a proper conversation is long gone. 'What do you think of this or that?' and you hit a brick wall. Remember what you had for lunch? and you hit a brick wall.....not her fault, please don't see the comment as being critical as it's the disease. So, AB offers a diversity of the serious (news/R and S and helping with info), the interesting, the chatter and cliques, yes the dreaded cliques, on Chatterbank, GMEB etc etc - and some good silliness and mental gymnastics - oh, and the crosswords from time to time.
And some of you out there, an empathy and even friendship builds - if that is creating a clique, so be it. How many ABers have I met, six of you and all super, maybe a couple more shortly so.
