I would be somewhat interested to see this question answered but as it is now I doubt it. It's really terrible.
Edit it and make it better! As of a few months ago, all users can edit questions. Users with <2k rep need to have their edits approved by users who do have edit privileges before the changes show up, though. On SO, two approvers are needed; on other sites, only one.
If you have enough rep to edit a CW post, go ahead and edit it.
If you have enough rep to edit a regular post, go ahead and edit it.
If you do not have enough rep to edit the post, flag it for moderator attention or leave a comment so that hopefully some others high rep users can take the time to clean it up.
