I have to agree with that. Though I think there are a lot more science fiction series being made and broadcast on major channels at primetime (looking forward to the Flashforward season finale tonight in particular, but also things like Heroes). There also seem to be a lot of remakes of older scifi (V, Battlestar Galactica, Day of the Triffids, the Day the Earth Stood Still). So I guess that following on from Geoff's comment it must be less geeky because there are more successful scifi shows and movies being made.
I might just be trying to convince myself there though :-)
