There is another reason why the RISC OS subsection of this forum is rather quiet, which I hesitate to mention, but which is evident from a glance at the intellectual level of some of its exchanges. Also there seems to be a strain of nostalgia for the BBC B computer and BBC BASIC which tends to swamp discussion of anything else. RISC OS has moved on, after all, but you would hardly guess it from this forum.
I still prefer to use RISC OS for as many tasks as I can, because I have grown used to its UI. I am very grateful for the hard work of the ROOL team in developing RISC OS for various new ARM platforms, in particular for the Raspberry Pi. If you find this forum a disappointing place for information about RISC OS, I would suggest a glance at https://www.riscosopen.org/content/.
