Please note that I took the liberty to downvote your question, because I think that
- the implementation of the 500 rep suggestion isn't worth the result
- everybody should have the right to answer homework questions and should make use of it
Like most of the regulars, I do help to close homework dumps. The decision usually comes very fast and no, it doesn't bother me.
But I do like to answer the good ones and it is fun, using hints, analogies, some drawings and the obligatory
spoiler :)
About 17% of my answers are on homework questions.
As Jan, Ben, and orthocresol have already agreed upon, this site is about quality, in questions and answers. I'm strictly against a low quality homework ghetto, or as Jan kindly called it, a playground for inexperienced users.
Users with less experience are welcome to give answers on whatever topic they chose. If somebody has just done a lab, he might very well be able provide useful hints on experimental procedures and their pitfalls.
However, in terms of quality, the same standards should apply to all answers.
As far as the homework topic is concerned, we often make use of the obligatory link on how to ask a good homework question. Do we need a similar guide on how to give a good answer to a homework question?
I think that common sense and the vault of editing wisdom are sufficient.
