Yes. Facebook search is poor. Mainly I suspect because the FB format wasn't really designed for such things as detailed discussion. However it has the numbers as it's still commonly used by people of my age to keep in touch with far-spread family members. A few of us did set up a series of posts detailing the coinage of Charles I on the The Coins of Charles I, King of England, Scotland and Ireland group, but even those seem to be buried now.
And yes, @Coinery that's the one. Though like others it's still a sales site for the admins there, it's a bit more active than many and has reasonably interesting content.
@Rob I think groups tend to specialise so they don't get swamped with content which, for most members, is of limited interest. Still get Roman, European and modern coins on the English Hammered group Stu highlighted above, but Admins remove them promptly as they fall outside the scope of that group.
There are places that have a broader coverage, such as Coin Community Forum, but even there they set aside sub-forums for different areas ...
Agreed. The setup here is much better for keeping tabs on things of interest and getting alerts for what's new. And yes, I'm on 'the internet' a lot. About 70 permanently open tabs, several hours every day .. and I still miss things that interest me at times. 😕
But then I don't go to coin fairs, so buying online or bidding, again online, at auction is how I keep building my collection. It's also easier than a trip to the British Museum or Library when I want to do a bit of research, so to me the time 'invested' is worth it ..
