The hotbed of thoughtful writing discussion these days is, of all places, LiveJournal.
Cath Emery on laziness and cultural symbols
Jane St. Clair on playfulness and bad sex in romantic relationships
Chelsea Polk on why writers hit a slump after their first publications
Elizabeth Bear on professionalism
… and Jennifer Jackson’s response
And then there’s the new For Writers collaborative blog, which picks up a lot of the LJ stuff, and Genre Neep, an LJ group with too many good links to list individually.
