I really enjoy the near-future scifi like Clarke wrote. Is anyone doing that anymore?

You also might want to check out the "mundane science fiction" movement:
http://bestsciencefictionbooks.com/mundane-science-fiction.php
A core value of movement seeks to reinvent Sci Fi. Mundane Science Fiction seeks to abandon the wondrous, and now nearly mythical, elements of Sci Fi--ray guns, aliens, distant solar systems, myth-like faster than like travel. Mundane Sci Fi favours stories about scientific realities--biotechnology and environmental change. Mundane Sci Fi prefers topics that are closer to Earth because Earth is really all we have. These writers wish to reawaken the sense of wonder of the Earth and the dangers it faces now.
Basically, Mundane SF deals with a very plausable future -- and a very near future at that. If a SF read features any sort of technology that's far out of the ordinary (light speed, wormhole travel, time travel, etc), than it's NOT mundane science fiction.
