One of the things I've noticed so far (and there were a couple obvious instances over the weekend) is that we've had a few issues with new users posting content that doesn't really fit some of the ideas behind Tildes (primarily, trying to focus on higher-quality discussions/content). This in itself isn't a bad thing or surprising, it's always going to happen. However, I think we need to try to think about some better ways to deal with it—it's great to have other community members telling people that it's not really the type of content they should be posting, but sometimes it's been done in a pretty hostile way, which isn't very good and makes the community seem unfriendly even though it's still very small.
So I'm mostly just looking for general thoughts about how we could try to improve the situation. Are there mechanics that we could implement? Should we try to get "what types of things should I post?" in front of new users more prominently? Could/should we have a "standard" way of dealing with new users posting things without realizing it might not be particularly welcome here?
Any other ideas or suggestions?
