I understand that the general consensus is that WordPress-specific questions should originate on wordpress.stackexchange.com and only be migrated to SO if they are of more "generic" or "algorithmic".
However, there are lots of new questions on StackOverflow that are wordpress-specific and still left alone on SO, for example this one, which is currently also has a bounty, so I'm sure many people saw it.
I personally feel that WordPress specific questions should be migrated to their specific site, since it will benefit both StackOverlflow and wordpress.stackexchange.com users. However, since I see that these questions are left as-is on SO, I wonder if I should mark them as "off-topic" or not? And if not, why?
