Having lots of points in these games means that the person has spent a lot of time submitting content, answering questions and commenting. I consider that this time would have been better used to write open source code, to directly teach neighbors, teenagers, friends or if the person is a real expert, to create a website with all the good advices, tips, tricks or simply contribute to a wikibook.

Why judge someone's technical merit on the fact that they find it enjoyable and stimulating to spend some of their free time actively participating in online communities?
