I mostly keep up with family/friends and participate in some special interest groups of the same general things for which I belong to forums.
I find that by and large, the groups where I interact don't facilitate the level of engagement as I get on a more traditional forum. As an example:
I do belong to Low End Mac(LEM), and it's mostly just a cesspool of people who look up to certain idiots who are doing stuff as the "latest and greatest thing" building on work that a bunch of us read and showed on Macrumors back with the PPC forum wasn't a cesspool.
Just yesterday, I was TRYING to be helpful when someone had just bought about 20 2,1-4,1 white MacBooks and was asking what the best operating system was for them. The usual bobbleheads said "Oh, derrr, they run El Capitan so you should do that." I said "The GPUs in these are terrible and don't have acceleration in anything past 10.7. 10.8 is moderately useable but with GUI glitches. I consider 10.6 probably the best overall on computers of this age."BTW, I was basing that on using these things when they were still reasonably current. I had a veritable swarm of bees saying "You're stupid and don't know anything about this so keep your opinion to yourself. Mine runs El Capitan fine except for(mile long list of glitches or things that don't work) and they have GPU accel since the graphics wouldn't work if they didn't." I bowed out...
Another-someone listed a pocket watch for sale that they were claiming as a "rare factory error" at a nutty price and it looked to me like it was built from someone's parts bin. I said that, and the guy selling it lit into me enough that, fortunately, the admins saw it and banned the guy...but still.
A few weeks ago I caught something fishy in another watch group. Someone posted a super rare but relatively niche watch and most people didn't have a clue it was anything special. Since I know there are a few people who collect that particular one, I screen cap it and send it to a couple. One calls me a few minutes later and says "Where did you see that watch, and was it for sale?" I said no, that the guy was just asking for information about it and that he was looking at it as part of a collection. This guy, who I know well, says "That one is sitting in my safe now. I bought it last year." I go back and mention that the watch can't possibly be for sale as that specific SN is held in a private collection of someone I had spoken too within the last hour, and the guy who it belonged to got equally irate and I can't figure out why...although the post disappeared a few minutes later.
Just a night and day difference from how I'm use to interacting in other venues...
