Worried about snooping on your visits here? Try https.
Just a reminder for those who would rather not share their browsing habits with corporate overlords: this entire web site is also available via https.
Now, if you work for a truly paranoid place which has installed its own certificate authority in all of your browsers and is using it to MITM https connections to see what you're doing, this won't make much of a difference.
Incidentally, the current (2011-12) SHA1 fingerprint for my certificate is: B9:28:71:48:3B:E8:19:9B:54:B5:B9:25:4D:48:53:E3:D6:82:8A:AF. If you're getting something else, worry.
