Today I've read a post in the Washington Post (sent as a link by a writer friend) in which the words of wisdom are these: if you write, then write under your initials and write about men, as that gains much more kudos than writing about women and their interests. click
There is an article in the British press on a similar vein here, though it does not go so far as to advise pretending to be male. It does bemoan the fact that insightful books on women's interests are deemed trivial - the very name "chick lit" being a giveaway, whereas men, if they write about similar interests from a male point of view, are reviewed, discussed and toasted as literary successes.
So for 2010, perhaps we ladies should try hiding our identities behind our initials, and see if it makes a difference!
