Philosophy of logic has an extremely low SNR in the real world. Millions of pseudo-intellectuals think they've solved Russell's Paradox or found a flaw in Gödel's incompleteness proof, while the number of legitimate new results these days is very small.
So any community that could discuss it productively would have to be invitation-only. The book "Exact Thinking in Demented Times" by Karl Sigmund talks about how the Vienna Circle (where many of the seminal results originated) had to carefully manage the guest list at their meetings.
For a field like logic where the important results are mature, it's probably best to just read books.
