I just saw a notice that EU laws require Blogger to tell people that they use Google Analytics and AdSense. It's not something I can block on my blog, but if you don't like them, you can block them yourself with a script filter. I use NoScript, which is a script filter for Firefox. I've used it for years and don't get viruses anymore. The only downside is that you have to allow pages you want to see and that gets tedious when a page needs multiple scripts to run properly, but you aren't sure which ones they are. That happens most for pages with pictures embedded from elsewhere or videos.
