The mapping community is still alive, it's just interlopers that is dead.
Come talk with us on discord, currently there's 200 people online and people talk about stuff all the time.
Phillip at runthinkshootlive is still hosting competitions too.
Then Black Mesa is still being developed and the workshop has some maps done for it too (I've done 2).
So we're not dead. Quite far from it.
