We all know technology has changed how the world works, careers, go, and so on and so forth. However I think one thing technology has done to careers – especially fannish and geeky ones – is that it's created an odd timeshifting effect.
Technology has the obvious effect of making a lot of things faster and easier to do and distribute to people. The upside of course is obvious – the downside is that EVERYONE is able to do and distribute more things faster. Everything is faster but the competition is the same – if not moreso.
