I put this here to prove a point. If this little sign can show you you’re IP and other information, then your information isn't as private as you might think.
Sure, I can't see the information about you it just shows me my own information. But every website you visit can, and most do, store this information in log files. This type of information is used for trending data. Web developers use it to get statistical information, so that they can better know what platforms to develop for. There are lots of other types of information that is obtainable also. Your screen resolution would be another type of information that is valuable to developers.
Jafo, or other admins, if you think that this is an inappropriate post, just Delete it. I feel that it is not, but I don't want to overstep my bounds.
Edited due to the fact that I forgot about the Delete thing.
