>You don't stand to gain anything from Reddit ever.
Oh come on, really?
I'm a hobbyist game developer. I frequent a few subreddits including /r/gamedev. It's a fantastic community and I've learned a lot there, and I've been able to use it for free promotion. It's been very valuable to me and I've enjoyed using it.
If your statement was "you don't stand to gain anything from /r/funny ever" I might agree with you, but this is just too broad a brush to paint hundreds or thousands of individual communities with.
