The Internet and the walled gardens

July 11th, 2007 · 2 Comments · general

Coding Horror saying what I’ve wanted to say for a while now. To add to that: Facebook allowed me to reconnect with some long lost friends. I’ve had some valuable conversations with these friends – on Facebook. Those conversations are not a part of my normal email archive or flow. I need my data to [...]
