Looked at the entire Penguin cover gallery ... and almost nodded off.  The cover for "Triffids" was completely devoid of the emotional impact of the early 1960s Fawcett edition.  The rest redefined the term "lame."  I simply can't imagine buying an SF novel without Lehr, Freas, Powers, Burns, Martiniere (God, this guy is good), Foss, Berkey, Schoenherr, Gaughn, Emshwiller, Whelan or the scores of others whose word adorns SF novels.

And why the hell does SF need more respect than it already has?  Personally, I like the ghetto and always have.  However, the mundanes laugh at us geeks and then troop down to the multiplex with the girlfriends that us nerds are not supposed to be able to get and drop $10 apiece (not counting popcorn) on the latest EFX-laden blockbusters, then hang with their homeys and play Halo 3.  SF owns pop culture, especially if you consider movies based on comics as a part of the mix (which I normally don't, but what the heck...).   Respect, re-schmect.  Give me a cover with a starship's guns, engines or both blazing and a cool planet, galaxy, mothership in the background and I'm happy.   Give the mainstream stuff to the mundanes who need something to read while they're on vacation or in the hospital.
