I completely agree, also about the article discussing "good art".
Though this applies to all kinds of contributions. My motivation to help with Ufo2000, for instance, died when they released a new version that rendered all the maps I made the month before unplayable. This was fixed at some later point, but by then I had moved on.
On a positive note, while reading, I recognized many things this project is doing right. Constantly providing new dev versions, for example, even for other platforms.
So... keep up the good work.
