A lot of the problems are solved if instead of trying to be the Master of Every Topic in 1001 discussions you stick to a couple of projects contributing there something that has to do with your skills.

If you are a user with attention to details and you like liqbase go and concentrate there, bugging lcuk pervasively not accepting easy eacuses from him.

Giving a shot to the app in 1h, commenting in a thread on ITt about your first impressions, telling the authors why they should prioritize that great feature you came up with and then vanish forever (while reappearing tomorrow doing the same on another app) brings almost nothing. Only noise and some % of non-satisfaction to the developers.

I was just reading yesterday that user saying that FBreader is great but without autoscrolling is just crap, the developers have no clue what users want and please hurry hurry tell me another app doing just that. Well, this isn't useful. Instead, it would be better asking what is the problem with autoscrolling (maybe it implies a lot of recoding, maybe the maintainers just don't see the point yet) or asking why it is low priority and what would be needed to push it up. And chase the thing until you get one day FBreader with autoscrolling. Because you pushed it and helped making it happen.

This is rewarding.
