Ok. Seems correct at first sight.

Nice.

Regarding reading, there is no particular issue so you can cache as
much as you like in your forum databases.

However, regarding writing (e.g. vote, new questions or new
responses), I think you should do them as early as possible otherwise
you might have coherency issues (e.g. the new questions conflicts with
the same one registered by somebody else, etc.). Only the demexp
server can guarantee a coherent state. You might cache during writings
but, in my opinion, this is very complicated and you'll have a lot of
tricky issues.

Yours,
