I agree, to an extent. This navel-gazing tends to precede a noticeable and rapid decline in quality, as the community becomes too focussed on itself, and less upon content and discussion. I've only been on reddit for just over a year but have noticed a marked decline in quality just in that time. Around this time last year, there were many discussions about reddit's declining quality and what's to be done about it. Now, about half the posts on even my heavily-culled front page are talking about reddit itself, half of the rest are using absurdly editorialized headlines, and there's a smattering of good content here and there. Heavy moderation seems to be key, as the mods quite simply don't seem to care anymore.
