Yeah, I've felt that I've been far more content with my social life ever since I stopped viewing socializing as 'making friends' but rather as 'Doing Thing X with other people' 
I have a different take for why that's the case though. A social interaction is like a story; it has to have a point*, a 'why are we having this conversation', a purpose beyond 'trying to make friends'.
You can have nothing but small talk with someone, but it's not going to want to make you come back for more. Unless you're forced into proximity with each other for other reasons (e.g. being coworkers or smth), that relationship isn't going to last, and trying to make it last (e.g. by reaching out and having conversations just to 'build/maintain the friendship', even when you have nothing to talk about) is going to feel like a chore. That friendship is a spook.
That's why I ignore people when they say 'hi' to me or ask me how my day was. It does not mean you're unlikeable as a human being; I don't know you! But you are invisible; right now, you're a 'background character' to me, a 'stock human'.
I'm sure there are very interesting things going on in your head and very likeable things about you, but I don't have the energy to take a shovel to your brain and dig it out; if you want to interact, you're gonna have to be the one to show me. And I know it's not easy; communicating those things is a skill, and I know what it's like to have a hard time because you haven't mastered those skills yet. (I hope that didn't come across as too harsh; again, I've been there myself and it doesn't make you a bad person at all :])
Personally, I would just continue talking about things you're interested in, and thinking up specific things you'd like to do because they're fun in their own right (even if you don't end up making friends with the people you do them with), and being like 'hey, I'm starting this (RP/forum game/whatever); here's how it works, have fun'. Prioritize creating activities over institutions (e.g. Discord servers).
* To elaborate, 'let's talk about comics because we're both comic creators' isn't really much of a conversational 'point' any more than 'it's cool/silly/fun/cute/etc' is a story's 'point'. I think it needs to be more specific, like 'what do you think of X trope? I have Y feelings about it'. This very thread is a good example 
I'd also argue that engaging with other people's work isn't actually a good way to make friends. This is because the natural 'point' of the conversation is 'their comic' (not 'let's discuss each other's comics, which is too general to be a good 'point'), but a lot of people are too wary of being arrogant/talking too much about themselves to shamelessly dive head first into this topic, but the most fun and energizing conversations come from all participants being shamelessly passionate about the topic.
(It's not a bad way to make friends, but it doesn't work the way people thinks it works, where they check out your work as well and have as much to say about it as you had to say about theirs and you have a symmetrical relationship where you're both interested in the other's work. But again, I'd argue that 'making friends' shouldn't be the goal here, but rather to just 'have an enjoyable interaction'.)
