Okay, I don't know how many folks use Gmail, but for those who aren't familiar, it's a free email service (like Hotmail) except it's run by Google. You get a ridiculous amount of space, and it's set up rather well, I think. The thing that is a little creepy from time to time is that the way Google can afford to offer such a great free-mail client is that they run text ads along the side of the screen. They're "smart ads" or something, which basically means Google uses its stellar searching capabilities to look for certain words in your emails and then the ads are supposedly tailored to your interests (or whatever it is you're writing about at the time).
Tom & I both had a heck of a time falling and staying asleep last night, and this morning I sent him an email to the effect of "Blargh, I'm so sleepy today." Upon receiving his reply, which said, "I'm sorry you couldn't sleep either," Gmail presented me with 4 text ads for...chloroform! Not Lunesta or NyQuil or melatonin -- chloroform.
