"First, it's quite amusing the turn around that Clay has made since his post two years ago about WiFi vs 3G. Suddenly the ubiquity, usability and versatility of mobile phones is a compelling platform and not something to be dismissed as closed and essentially redundant as he originally wrote.

• This is one of those cool, scary things about blogs. All the sudden something you wrote several years ago is easily found and distributed in a matter of seconds. Said something bad about X 4 years ago, no problem, I can find the link plus 10 cached versions in case you take it down.

Overall I think this is a good thing, but sometimes people do change their opinions on things and it's very easy on the web to link back to a specific point in the past without considering or reading anything that has occurred since then.
