Thoughts on answers
It seems to me that after looking through this set of evaluation Q&As that the most common deficiency in answers is the lack of references. Many of the homework and everyday chemistry questions can probably be answered with an appropriately phrased web search, and oftentimes when I find a question that I don't know the answer to but want to know the answer to, I just do the search and report back to the OP.
Even though many questions asked might be answerable with a little bit of work on the part of the OP, I nonetheless find it valuable to have a collection of chemical information in one format that is familiar. It would be nice, however, if answers included a summary of references (preferably expanding beyond wikipedia) that were used in crafting the answer.
Thoughts on questions
As for questions themselves, I wonder if we are starting to get to a point where we need to consider the presence of duplicates. Recently there have been a lot of questions based on electrochemistry. As an electrochemist, I welcome these questions, but I wonder if we need to start referring future questions to asked and answered questions. Take Galvanic cells for example:
All of these questions are technically different from one another, but those with expanded answers all provide (to varying degrees of correctness, thoroughness and clarity) the same information about Galvanic cells. Do we get serious about a duplicate policy or is there perhaps a special tag that is used for general concepts in chemistry.
The Community Wiki Content Map
Another possibility (and I've now gone a bit off topic, so I'll keep this short) is to consider a set of community wiki questions that are based on the American Chemical Society Exam Institute content map. This would allow us to build a resource of general chemistry information that members answering questions can refer to when answering questions. If there's interest, I'll start a second meta question to flesh out some details of this kind of process.
