Reddit is often at the top of search results for tech. It maybe pozzed to shit but it does have content and if you just want that there it is.
Facebook is used universally so people naturally gravitate there. Unless you have a reason not to be, you're on facebook these days. It's replaced the telephone in how normies communicate (but they use phones to do it). They get recommended communities so they get a bunch of what they like in one place. It's also full to the brim of pajeets and gooks who push numbers through the truth even though their posts amount to "Where da white womyn at". Facebook becomes even more insidious because it works at a local level. People start using it to discuss local events exclusively so you get on or you have no idea whats happening around you.
Discord is easy to set up a room and have all the features a modern chat room wants. All it lacks is a sync youtube videos option and it's an all out media package for most "tech savvy" people. This has been made even worse by everyone and their dog making a discord channel to build a "community" around themselves.
Google plus was one of the better community sites because it was so unknown for the most part. The hobby communities there was almost exclusively male and full of passionate people who were looking for a community. The others are much more casual and easy to discover so took the brunt of the casual invasion.
