Nevertheless, you don't see the PUA community frequenting reddit.com/seduction. Don't know the % of them who actually know what Reddit is. I don't know of any one true "base," for lack of a better word, to find good PUA content (ex: TechMeme for tech news).
The fact that there are 56 heavily-populated PUA forums deserves some attention. The fact that forums are still used deserves attention. There should be a better platform to address questions, share stories, and share links.
Many blogs like Zen Habits don't offer fostered conversations. Zen Habits doesn't even offer commenting, resulting in a subreddit with 6k subscribers: http://www.reddit.com/r/zenhabits (many of which links aren't from zenhabits). Lifehacker doesn't offer much fitness-related content (How can I bulk up quickly? etc). They tend to aggregate everything as well -> too much noise.
I'd have to go with Posterous. There's a menu on the side of the front page where you can easily alternate among your blogs. Easily editable settings, no need for tuts to figure anything out.
