OK, U asked 4 it.... I've bn reading science fiction & other weirdness since 1971, when I was 12 yrs old & my parents threw some 2nd-hand copies of ANALOG magazine & other SF magazines at me, followed quickly by Raymond J. Healy & J. Francis McComas's huge landmark SF collection ADVENTURES IN SPACE AND TIME. I haven't looked back since, tho I liketa think my tastes have Xpanded a bit....
I haven't read everybody -- there's a lotta people I've never read, & I can give U a list -- but I've dug around pretty widely, from Asimov 2 Zelazny, Heinlein 2 Ellison, Niven 2 Moorcock, lotsa classic old stuff, little bit from the '50s, lotsa '60s New Wave & '70s stuff (4 part of the late '70s I was reading almost everything in the magazines every month -- ANALOG, GALAXY, F&SF, ASIMOV'S, the rest), started slowing down in the late '80s, & only bits & pieces since.
What follows is stuff I remember knocking me over w/ its brilliance, inventiveness, vividness, involving-ness or un4gettability, stuff that won't waste yr time, no matter how old it is. (It's also a good memry test 4 me 2 C how mucha this stuff I can remember off the toppa my head.)
