Muffs is hands down the best resource for modular info on the internet. I use it more as a library now (using the search) and don't post too often. When i started getting into modular about 7 years ago, it was invaluable. The B/S/T section is invaluable. I think you also need to differenciate between the different sections. I goto the Ciat / Buchla / DIY / Modular Synth General / Eurorack sections. I think the Euro section is what a lot of people are referring to in the above comments. It can get fiesty on rare occasions, but 99% of the time its fine. I think its got what i call more "gearsluttish" in recent years, i think thats down to the popularity of Euro and more people from other forums being involved. I welcome the ban on political talk - its a synth site! Take that stuff elsewhere, it just causes fights and disharmony.
On a side note, i've not been using Facebook very long, maybe 1 year? I realised quite quickly i needed to narrow down what i was seeing in my timeline. The US general election was the perfect example - i unfollowed / unfriended multiple offenders posting about politics (on both political sides). Brexit was the same. Seriously, i'm not interesting in their personal political views clogging up my timeline and ruining my day. Its my life and i choose what i want to see. Similar to what the news corporations choose what they want you to see. Everyone has their own agenda.
The good thing i like about facebook is keeping up with family which i have dotted around the world. Also the groups sections, there are is some good stuff on there especailly the Modular DIY and Ciat groups. I have 2 facebook accounts - 1 for direct family and a few close friends, 1 for modular stuff, general news and interests. I don't mix the 2.
I like Instagram - modular synth vids and Cats all day, no snide comments, minimal talk, a lot simpler and rewarding.
This site is good also, but it can get very techy for me. Theres seems to be a lot of computer geeks and coders to the fore and very poltical savvy people also. It seems less about the music and more about the tech. It can be a little intimidating to the less computer literate guys, but still everyone here is friendly and helpful.
The reason i left the monome site 7 or so years ago - i wasn't making any music, just beta testing peoples monome creations on a laptop with 101 different VST and VSTi. Music making wasn't fun.
I came back recently to Monome (i dug out by 40h) for the modular modules. I'm more into the making music side and less about the computer / programming side. The fact i could use my monome again, without it being attached to an email machine on which i wrote crap music previously, brought me back
