Do you know any steam groups with active members in chat rooms?

When i joined steam, i still was a kid evolving into an edgy teenager and obviously i was broke asl and didn't have money to buy games and asking my parents for money to buy them was outta question. But as i grew up, i started paying attention to the steam communities, market, discussions and all that stuff but i couldn't seem to get my way around steam groups because all that where "within my reach" (the ones from people i had added as friends) were inactive, or had 3 people or were made to trade CSGO items.
From time to time i joined some groups because of they had a funny name or just to have some funny group to display on my profile, but i never really thought of them as a "group" of people until i joined one called "literate gamers" which is kinda ironic but is dead apart from the fact that from time to time someone sends a message.
That got me thinking, how many groups with active people are? I really like the idea of chatting with some random people, it reminds me of MSN messenger in a way, plus my friends aren't into games stuff that much and i don't really talk with people about the topic, so i thought it would be nice to have people to do it from time to time. If you know any, it would be nice to know !!
