I really think this is going no where.
Welcome to the club.
I'd love to find a forum where it's less crowded with a lot more technical discussions. Ideally people there don't care about levels. There are new technologies being discussed.
There is no such place. If you want to follow technical discussions, then:
a) Follow the Bitcoin development mailing list.
b) Follow the Lightning development mailing list.
c) Read the #bitcoin-core-dev IRC channel.
d) Read the #bitcoin-dev IRC channel.
e) Read the #lnd IRC channel.
f) Obviously, (as you've mentioned) pay attention to the Github repos.
I checked out Ethereumtalk.org but it's nothing.
mETH is a centralized shitcoin, don't expect proper technical discussion there.
Just like bitcoin itself, it's up for fork when the community can't agree.
That won't work.
Seriously, can't think of a better use case for DAO than such a forum!
Horrible idea.
