Reddit really is not a forum at least I think its more like a news sharing site where people can comment a small amount on their reaction instead of being a forum. The Bitcoin reddit community is not as in depth as Bitcointalk for sure and as a platform is very flawed because people can just create multiple accounts and upvote a certain agenda to get exposure. Bitcointalk at least does not have a broken upvote system.
I've met quite a lot of interesting people on Twitter that seem dedicated to building projects. Not so much on reddit. Twitter is a great place to discover projects of all kinds though. You can search around long enough and find people with the same passion towards an idea that you may have and be exchanging instant messages in no time. It's refreshing. The platform isn't the best for working together with groups, but that's why things like Slack exist. This forum has it's uses, but it's userbase of contributing members does appear to be shrinking and projects here that actually interact with the blockchain in some fashion are endangered on the way to extinct.
