Alright, so when I come to the discussions I see the following types of posts:
(80%) People complaining about Valve and VAC
(10%) Ways to improve CSGO, interesting concepts
(8%) Actual discussions
(2%) Spam, other

So lets talk about the 1st type of post.
Now a lot of people encounter cheaters. Everyone says that they flood this game! I can safely say, that this game is not full of cheaters (UNLESS YOU PLAY CASUAL). From the around 400 games I played (including Wingman) I can litteraly count on my fingers the amount of cheaters I encountered. Prime is not actually that necessary if you have a good Trust Factor. If you encounter a cheater, kick him. VAC is also good, it catches more hackers than tou make spermatozoids you make in an hour.

2nd type. A lot of people have ideas to make CSGO a good place, they usually think of something others couldnt think of. Others are silly for example, DZ Ranks, because that gamemode is RNG.

3rd option. There people actually discuss, they argue on whats important (most of the time it comes to a Flame War). But those also help to the discussions and community overall

4th option I dont even need to talk about, mostly troll posts or other off topics, posts with some kind of a guessing game for example I will guess your rank ones

So this was the summary of CSGO discussions if you want to know what to expect here.

Phew this took a long time to write, even harder on a mobile...
