I've never asked a question on Stack Overflow before. But I've been to SO quite often after Googling for answers to my questions. And every now and then, I end up at these great questions which I would love an answer to, but I find the answers unsatisfying (or just nonexistant).
I also write blog posts about my "hard to crack" questions once I've found my answer (usually through hard work; there's no point writing a post about someone else's work unless I add something). Now I would like to "contribute" this post back to old SO questions which failed me, so anyone else Googling for the same question and ending up on the old thread will see my blog post.
But it feels like spamming, especially if it bumps the question to the top and notifies everyone unnecessarily. Chances are, the OP doesn't need an answer anymore. The people I want seeing my answer are those who, like me, happen to get there through Google.
Is it okay for me to answer with blog post links on old/dead questions here on Stack Overflow?
P.S. I already read this: How to refer to your blog when answering?
I want to know about posting answers on inactive questions.
