Slideshare.net

I get caught up from time to time in a great site, Slideshare.net. If you haven't heard of it, it allows people to share their PowerPoints and similar work (as if we didn't have enough PP pollution, already, huh?)

As you can imagine, there's a fair amount of dreck, but then there are things like David Armano's excellent look at marketing and the online experience -- hint: editors and publishers need to pay attention.
