That a question attracts a lot of answers on a site doesn't mean that it's on-topic there. Sometimes users are enthusiastic. :-)
The moderators of ELU asked about migrating to us (I guess it was going to be closed there) and we accepted. I hadn't noticed the large number of answers at the time. If any are not suitable answers by this site's standards, please flag them.
It is a frequent source of frustration to me that posts migrate with their votes intact; it can really distort things on the receiving site. This request on Meta Stack Exchange was declined some time back, but maybe if enough (more) people lobby for it, it might help?
