What if you're searching for a birthday gift for your wife, or planning a surprise getaway for your anniversary, etc.?
Yes, I know about I the incognito modes, running browsers in a VM and resetting the VM, etc. I was just pointing out legitimate things that you would want to hide from your spouse and that your spouse would most likely be glad to not find out about (depending on how they felt about surprises...)
The good thing about putting the book review on Slashdot is to potentially give a "heads up" to folks about a book they may not have been aware of. In my case I am now aware of this book and it is a topic I am interested in.
I didn't even read the review. I look at the rating and if it is reasonable (usually 7/10 or higher), I'll head over to Amazon to read the reviews there.
With your bare hands?!?
