Isn't this idea dead yet?

Apparently not. At least, not if this article on Slashdot is any indication. But, c'mon, how long have "tip jars" and the "Donate Now" buttons been around? It seems like forever to me. And, does anyone ever do it? No. At least, I've never heard of anyone actually doing it. I know that I have never done it. And, what's more, no one has done it for any of my websites, either. (Of course, I didn't expect them to, but still...)
Yet, the hopefulls on Slashdot seem to think this could work. Well, dream big, I say. Dream big.
