Q:

What if I didn't really *get* an answer?

The StackExchange sites, as we all know, promote accepting answers to questions. People tend to dislike answering questions if the OP has a low accept rate.
However, ignoring for a moment the problems of relying on someone who by definition knows less about the subject than the answerers to decide which is the "right" or "best" answer... sometimes I ask a question and don't really feel like I got the answer that I was after. But then I have to choose the "closest match" or suffer a low accept rate.
Could there be some alternative to this scheme? Some way to indicate that I haven't abandoned a question without thought, but that I genuinely didn't get the answer I sought?

A:

An acceptance rate of 80% or higher is still, in my opinion, a fine acceptance rate. Even the coloration of the text helps people to see that it's not really a bad acceptance rate until you drop quite a bit farther. (I believe the text is green for 81%-100%, grey for something like 21%-80%, and orange for <=20%)
I know that "100% acceptance rate" looks good, but I think that those who you want answering your questions understand that of course sometimes the answers you get aren't good enough.
If, on the other hand, 50% or less of your questions are getting answers, but not reasonable answers, I think you may have to blame yourself for bad questions (or unreasonable expectations) and not the system.
In short: accept that you might not be able to keep 100% acceptance rate. I do.

A:

There are a few buzzing noises who love to harass people with low accept rates. Every time I see one, I flag their comment. 
I wish I could contribute to a larger penalty. In other words, the solution here is to discourage harassment. 
I really doubt that there's any shortage of people who, in fact, answer good questions regardless of accept rates.
At the same time, it is true that there is sometimes a correlation between very low accept rates and very bad questions.

A:

You don't have to keep your accept rate at 100%. Green is sufficient ;)
The systemic solution to no-conclusive-answer-yet is opening a bounty.
Another option is to keep editing the answer. This is what I would recommend here. Oftentimes the lack of an answer means you could add more details (or remove others for that matter). Make it prominent like Update 3:
You can also add a hint like [Temporarily Accepted Answer], if it really itches you to tick one. To make it look less rude, maybe add a community wiki answer of your own (but with at least e.g. solution hints or a recherche summary) and mark that as temporarily accepted. (That's what I did for one of my questions where most likely no solution exists yet.)
