Did you noted, that Xamarin.Forms will pass Xamarin.iOS in a few days regarding postings (today 26.4k vs 26.7k) and also will pass Xamarin.Android in no time?.
I further have seen, that there are about equal (or more) active users in the XF-Forum as in iOS + Android (together).
This all, although XF is available - I think - not a full year now.
So… let’s hope that Xamarin reacts and increases the XF-staff accordingly (XF-development, XF-support, XF-bugzilla, XF-documentation and - especially also XF-VS-Integration -> debugging!).
