It's interesting the facts that can be gleaned from Sitemeter. As Henry found out recently when he noticed that someone working for Swiss govt had dropped in to read his blog.
Now the other side of this coin is that other people can 'snoop in' on your sitemeter statistics. Are you aware of this fact? If you want to test it out get a friend to look up your blog on their PC and click on the meter. They should just get the summary page .... If they don't then you need to configure the privacy settings. Don't forget when installing the meter to go to the Manager Page to change the default settings to a more private level. I've found a surprising number of bloggers with sitemeter up and running who don't keep this information private. It may be they don't care ... but I would hate to think that some bloggers may not be aware that this information is out there for any nosey-parker like me.
If you want to keep your statistics and visitor stats private do Remember to go to Manager and then Privacy settings.....
