I personally try to whip questions that might be well received on ELL into shape by editing the post; fixing typos, tags, and maybe even their titles. If we all did something to make an ELL candidate question at least look presentable that would help enormously. 

Proofreading questions should never be migrated. Bad questions or questions whose answers can be found in a dictionary should be closed for... lack of research. Yes, sometimes that reason is the "best" reason for putting a new question on hold. They should not be dumped at ELL. If a duplicate can be found, even better.

Unfortunately, good questions that are better suited to ELL tend to attract upvotes and answers on EL&U. Which leaves me to urge the mods to migrate good learners' questions faster, but only *after* some makeup has been applied and a  proper pair of shoes have been provided.
