I had a search on various metas, but couldn't find an exact answer to this.
Occasionally there are posts, such as this one Disproof mitochondrial eve is 6500 years old, that are poorly written and generally don't follow the conventions of how to write a good post. It has rightly received a couple of downvotes (although not from me).
However, I think that there is an interesting biological question to be answered within the post, despite the post itself being in a poor state. I had a go at editing the question, since I also quite fancied doing some research and providing an answer.
My question here is:
Should I leave poorly formatted/written posts with little effort shown to be downvoted and left to die and be closed, or should I go ahead and edit the post and try and 'resurrect' the question in the aim of giving (what I hope) is an interesting and useful answer?
