Right now though, this is very much a discussion around embedded arm boards
and probably will remain so for the foreseeable future.

I'd say there is a very large overlap between current arm discussions and
embedded discussions. Most of the users will likely be on and benefit from
both discussions. Combining them would be a practical means of ensuring
increased communication and awareness in those communities (see Marcus'
point re low volume sigs going nowhere).

Of course, if the interests diverge and there is sufficient critical mass
for an arm sig, then yeah - of course a rethink would be practical.


I don't what this to digress into a 'definition of embedded' thread. But as

It's in the overlap. There is zero overlap between OSX support and other
sigs.
