As the maintainer of a reasonably popular library, I actually get irritated by a lot of 'thanks', because they are in the form of this sentence: 'Hi, can you implement ? Thanks!' Usually from people who have never contributed anything. Honestly, being thanked in any shape or form does nothing for me, Id rather have users be more considerate of our time and not abuse issues and the community for supporting their lazin…
1. Severely restrict the scope of the project (i.e. do one thing and do it well) 2. Don't feel guilty about saying "no" 3. Realize that people have no malicious intent or are lazy when they request . It's just like a normal customer in a business: they often have no idea of the cost and difficulties in implementing things. That's okay, it's my duty to inform them of that. 4. Refuse pull requests for features that I don't feel like maintaining. I always try to keep people from wasting their time and ask them to confer before implementing a feature.
I don't feel animosity towards people who (even rudely) request such things. But they can expect a short reply in the form of "I'm sorry, that feature is outside the scope of the project / is going to take too much of my time."
