One of the troubles with philosophy is that half the questions can be directed elsewhere. "Ah, that's a language problem." "What you're talking about is a quirk of mathematics..." "That's a psychological question really"
Another problem is that there just aren't many users. The answers and question edits are solid but there really aren't many people around there. I see the same three names in pretty much every question. Their chat is deserted. 7 days without conversation. 4 days without conversation.
