Besides the reasons you listed there are other reasons for not accepting answers:

• OP hasn't been able to put the answers to the test yet. They may look good but only trying them out will tell whether they were the right way to go or not.
• You got less concrete/technical answers than you were hoping for.
• "No good" is a bit subjective. "Unsatisfying" seems to apply more to the questions that I haven't accepted an answer for yet.
• The answers on offer seem like guesses, opinions, hunches etc, possibly even the result of one of our "get rid of unanswered questions" drives.

It shouldn't matter much anyway. Stack Exchange always says it's not about the OP but about the lasting value of the Question and its answers that are important. In isolation, "acceptance" is just a statistic with more relevance to reputation that usefulness of the QA as a whole.
