I was looking through some of the questions I've answered, and an unsettling amount have:

• Not accepted an answer
• Not given extra details to help people answer

In essence, these questions are now dead in the water. Would it be proper ettiquette to post a comment on the question reminding the OP to accept an answer or provide more information? There are a couple questions out there why myself and others have put a nice amount of work to make a well informed and well edited/formatted answer. When the OP doesn't do anything, it's kind of insulting.

I don't mean this from a reputation point of view, but more from a "we are a question and answer site, not just a question site".

Example (I added this comment, does this work?)
