I'm branching off on something different here but you said anything goes as long as it's got to do with maps right
The biggest problem that I see with the foundry is the lack of updates to improve it. But It's also something that we can't do much about! We can state our opionons and give suggestions on what we would like to have but that's about it. We're not going to get anything by striking or going on and on about what we'd like to have.
The second biggest problem the way I see it is that there are too few people in the foundry. There's a group of about 20 people who stand for about 99% of all posts here. This is not good for creativity. But unlike the lack of updates from lack, this isn't something we can't do anything about! I think we need to be more selling! Instead of just making a map and dealing with the feedback we get in that thread we could try to bring people to our map threads. How about PM'ing random players on the scoreboard that you're making a map and would like their feedback on it?
I'm sure this would bring in a lot of people who's never been in the foundry before. Maybe their advice wouldn't be the best but some would probably stay and later learn how to give good feedback. Who knows some might even take up map making. If we all did this I think we could make a difference!
It's no different from tournament organizing really. You want players to join your tournaments, and you want players to comment on your maps.
