A note about the Google toolbar from WebPosition Gold:
"Unfortunately, Webmasters have reported that this toolbar records a cookie on your hard drive that can be used to track your surfing activities and could be used to associate you to the IP address you use, even if you have a dynamic IP. At least in one instance, it's been reported that Google used this cookie feature to track down the author of a program that reported PageRank without needing to run the toolbar program. Google demanded that the author remove the program from his site. Therefore, although the toolbar can be useful, you should be extremely cautious about using it. Google could use it to track your activities or associate such activities to other things you do such as submissions. If you wish to play it safe, consider avoiding the use of the Google toolbar."
