Every single time I wonder why updates are slow, the conclusion comes to: valve won't hire and people won't join the team when they do.
So what about the people in the community who are constantly making new items and maps?
I can't claim that I know anything about the skill of new people, but not hiring people who are right there seems like a gaping hole that leaves comsumers unhappy for no benefit.
Also, the whole other-teams-want-more-too shouldn't be a problem either. Just hire more, the other games are even more popular than tf2 and have more people willing to help development.
Why is this such a problem for valve's hiring?
Whatever, I'm probably too stupid to understand this anyway.
