Is it "Private Info" when some dingbat has broadcast it over an unencrypted wireless link, then?
Nice to have some fun at Google's expense here - but people's reaction to this mystifies me, it really does.
Let's take a minute to consider what happened: -
1. People set up wireless networks
2. They didn't encrypt them.
3. They transmitted data over the resulting unencrypted wireless link.
4. Google recorded the data.
On the one hand, sure, there is a privacy issue - but it comes from Google's ability to aggregate data, rather than the "private" nature of the data - I really think that after you have transmitted your data over an unencrypted wireless link, you have to accept that it's a push to describe that data as "private", and that you are the one who has made it public!
We need some sort of "Date Protection Darwin Award" for this one!
