I wonder if the community would find it appropriate if I ask a question like
Is this or that known? It would be interesting for this and that reason. For details see our blog "blah" where we ask for answers as well.
The main problem I have with posting it here is that I am less interested in just having an answer, but more in pointing people to the blog post.
If I follow http://blog.stackoverflow.com/2011/07/its-ok-to-ask-and-answer-your-own-questions/, then I feel like it's totally okay posting the problem and the blog post directing towards an answer. I will write a follow-up meta question about that...
