I've had a strange experience over the past year, and it's getting more common. As a developer, I used to be the one recommending software/tech things to my friends. Now all my non-technical friends have started recommending things to me that they have discovered on the intar-web. The trouble is, they're almost all closed systems - apparently free, but under the control of one group.

It started with Skype. Then xanga. And most recently it's been facebook. The speed with which facebook has spread amongst various of our friends is impressive. Some things about it are really good too - they're beginning to understand the sorts of things you can do with the Web.
