If I visit my blogs on the road, I see them as any other user sees them. I can't edit anything without logging back on. When you use a foreign network in hotels, airports, or other places, you need to be very careful not to expose yourself to things like this. It would be child's play for a Wi-Fi service to intercept everything you do on any site you visit, and I expect that some do exactly that.

On wi-fi systems you do not own and control, every password you enter from your keyboard may well be captured. Think about things like your online banking, for example. Do not trust wi-fi networks you do not own and control. Basic computer safety.

They make more money, though, selling information about your browsing habits. Google, Yahoo, and Microsoft do the same thing. That's why you see those neatly targeted ads on all those sites.

A little over a year ago, I did a the text content for couple of websites for a swimming pool company. In the process, I went to a lot of swimming pool manufacture and accessory company websites. For six months, every blog I visited had an ad on it for some swimming pool company or another. Google, through Chrome and the search engine, decided that my IP address was really, really interested in swimming pools, so they served me a really, really big batch of ads from swimming pools builders. It was funny, to say the least.

They don't really care about you, personally. They only care what you do on the Internet, so they can sell companies on advertising directly to you. Makes sense, if you think about it. They're targeting ads to an individual IP address. Very clever of them.

They can't spy on it if it's encrypted.

over wi-fi, too. A guy really needs some serious anti-malware stuff working to catch such things. A lot of people more or less ignore security on notebooks and other portable devices. It's a mistake.

Which makes this kind of behavior even worse, because you 'paid' for that feature, it might even be why you chose them over another hotel.

Whenever I'm not on my home network I'm much more aware of how insecure/unsafe it might be. The first thing I do upon returning home is to change all the passwords to any site I've accessed from a 'foreign' ISP. Of course there are some sites I won't use while on the go like banking/credit card.
