Yeah, the premise is solid - it's actually become MORE relevant in the decade since it was first written. I go in, and put a few updated technical notes and such. For instance, the reality show craze didn't exist when I wrote it, now I've crafted it so that the reality show craze helped to CREATE this near future world.
Likewise, I have a time travel piece I wrote back in '01. Every now and then, there's an advance in quantum physics, and I go adjust the dialog a bit. Keeps it current.
I have a romantic comedy that is in the hands of an agent/packaging Pro Co. When I wrote it, the internet was in it's infancy - and a big part of the plot was trying to locate a 'long lost love' - now of course, Long Lost Loves stalk us on Facebook - so I had to adjust some of the plot elements, but again - the PREMISE is solid - so people seem to like it.
