I'm asking this in light of the Beta site closure announcements question, but I don't want to steal its thunder.
Realizing that we share at least some of the subject matter in common with the proposal for http://area51.stackexchange.com/proposals/38069/neuroinformatics, would it make sense to absorb this Area 51 proposal? I, personally, would enjoy seeing more neuro content on our site, and I know that there are a handful of others as well.
Not many here may be steeped in (or interested in) bioinformatics, but I think that the neuroinformatics would involve more issues related to anatomy and physiology than the data and genome crunching that bioinformatics proper demands.
I don't know if this would gain us a larger population of users, but I think it would gain a set of people who were passionate enough about it to propose it on Area 51, and who could likely be active contributors our site. Some of them may not even know that we exist.
