Clay Shirky has written a fascinating piece on social software. Here is a short excerpt that particularly amused me:

Why did we get Geocities and not weblogs? We didn’t know what we were doing. One was a bad idea, the other turns out to be a really good idea. It took a long time to figure out that people talking to one another, instead of simply uploading badly-scanned photos of their cats, would be a useful pattern.
