Many have observed that during the early days of the site, standards were still somewhat in formation, and many older posts lack the quality that would constitute a valid answer, sometimes asking follow up questions or pointing out that they don't know the answer but hey here's what I had for breakfast. A lot of these answers are even upvoted.
Here's one example.
Should these be flagged for deletion and deleted as they are stumbled upon (since that is what would happen to it if it were answered now, it would be downvoted and then deleted by the community or a mod)? If so, any particular flag, or a custom flag?
I'm not suggesting a search and destroy mission, just the enactment of proper procedure upon noticing these posts.
