From time to time questions get asked on math.SE which may be quite suitable for MO. Given the current climate of math.SE, such questions may not receive the attention they are due: e.g., they disappear from the front-page before someone with the requisite knowledge to answer them even sees them. Currently, it seems that the best way to get answers to these lost questions is to migrate them to MO (or simply cross-post them). But I can think of at least two arguments against the migration practice:

1. the general SE guidelines for migration are that questions which are on-topic on the original site should not be migrated away; and
2. removing more advanced, and IMHO generally more interesting and well-composed, questions further decreases the overall quality of math.SE, and, if continued, may result in a situation where such questions are simply no longer asked there, effectively turning math.SE into undergrad-math-homework.SE (if it isn't already).

As an end-run around these two issues, I am wondering if it might be possible/acceptable to create an "interesting (and unanswered) questions on math.SE" thread here on meta.MO. The intent would be to advertise (unanswered) math.SE questions which may be of interest to members of the MO community, and ideally to have these questions answered on math.SE.
