Thar be dragons...
Be careful. One aspect of your question makes me think you are finding questions such as, "What is the best WIDGET program?", when you happen to sell a widget program.
The problem is, those questions tend to be old questions that just have not been seen since our question standards started to disallow such 'shopping' questions.
What this means is, posting an answer to such a question might not only get you in trouble with what Aaron's answer notes, but you might end up finding that since you have 'bumped' the question by answering it, it ends up getting closed.
I am focusing on 'shopping' questions here, because of the way you stated that your product "is the answer" to some questions. Nothing I say here is meant to contradict Aaron's answer.
