But your milage might vary and if you have to struggle and beg for those donations, you are probably right. Time may be better spent elsewhere. I can't see Zed having that problem!
The donations serve two purposes: They make it so I can work on Mongrel2 for a while and get something awesome started. It also demonstrates that other people are backing what I'm doing. When you don't have a large community at the start, people will take monetary amounts donated as a sign that the project might go somewhere.
I can't say I agree with folks who judge a project's success by donation amounts or community size over technical capability, but I can understand it.
That alone makes it well worth it to me. I'm not going to donate because I've never used your stuff, but if that's your goal then it's a noble one. Good luck!
All he's asking is that some, especially the ones who are profiting from it and can afford it, donate a little something back.
