I've taken a similar approach for reading sci-fi/fantasy, where authors/publishers seem obligated to make everything a trilogy. I'm tired of reading a great book and waiting years for the next, so now I just don't bother until they're all done. If they're expecting to use the first book to decide whether to do the remainder (which seems rare) I'm not helping the situation, but hopefully I'm voting with my dollars that writing standalone books is appealing.

There's enough good stuff out there, or series being completedthat even at 20-30 books per year I'm not lacking for anything to read.

I'm looking forward to reading The Kingkiller Chronicle, The Stormlight Archive, etc. ... someday.
