The conclusion I've come to is that there are a large group of people out there who want to get something for nothing, no matter what. It doesn't matter that the points don't cost money. They have received help for FREE.
I've broken the question posters on the Q&A site into 4 main groups:
1. Those who ask a question and never bother to rate any answers (or award points) and leave their questions open for ever. These are also usually questions that could have been answered if the the poster did a simple search on one of the many Internet search engines
2. Those who close a question and reject ALL answers (thus avoiding awarding any points), even though one or more answers are obviously correct). A subset of this group will actually comment that the answer helped but still reject it.
3. Those who properly award points and close their questions, but with no feedback
4. Those who properly award points and close their questions and do give feedback/thanks. A subset of this group will actually send you a personal email (if they can) to tell you how thankful they are for helping them out of a tough situation.
I will admit that there are probably a minor number of people in the first 2 groups whose behavior can be explained by simple ignorance of how this forum works.
For me, all it takes is a couple of people in the last category to make up for all the rude people in the first two categories.
For Jellimonsta: about the "Answered" status of a question - thisis basically just a Yes/No type of filter (either there has been an answer posted or not). There is no implication as to the "quality" of the posted answer. This filter is used so that a user can filter the types of question they wan to look at (i.e all questions, only questions that have answers posted, only questions that don't have posted answers). And no, TR doesn't do a good job of explaining that fine distinction.
