User blog comment:Mineko Charat Lucky/Wikia Blog Guide: What makes a blog, a blog?/@comment-5481660-20130425195130/@comment-5791947-20130425202223

That's because a question is not a blog. The definition of a blog is "a discussion or informational site published on the Internet consisting of discrete entries". The existence of blogs is to share your thoughts, not merely asking others for their thoughts on the subject. Answering a question does not qualify as a discussion, as the owner didn't even contribute any of his own thoughts for that matter.

On the other hand, the same or better effect can be achieved with substantial blogs rather than just a question, just so the information may (or may not) be useful to the readers.

Even if we go by your idea, there's no "meaningful powerful questions" ever asked so far that's worth staying, as you can simply get what you want by asking on that particular topic's page, or on chat.
