I used to post my pages there, it got some eyes, but I stopped after a year or so, and instead I only post my joke pages, which do decently. One of my joke pages made it to r/all and gave me a huge early boost.
Recently, r/comics has gotten a bit dominated by highly sexualized comics, which I don't really enjoy, but it is still best at slice of life family style one off comics with repeating characters. Posting times are also a big deal there, but I'm not an expert on that.
If you can tell a complete joke in 6 panels or less, and your art is eye catching, it's a good place to be.
I'm planning on running an event/contest of sorts that involves r/comics later this summer (July)! I hope the other members of this forum will be on board with that sort of thing.
