PGP while a decent technology is very cumbersome. Worse, it's easy to shoot yourself in the foot if you aren't an advanced level user. I've used it for years on a regular basis with various implementations. It's just never been user friendly or easy to use. If it was more user friendly it might have had better adoption rates. As moxie has pointed out, we need something better for the masses, it looks like we are finally seeing progress towards that goal now.
