Yahoo sucks. They sued Facebook for patents. Sigh.
I would be up in arms if that's all there was. If patents weren't already gumming up the works in other areas.
And anyway, why should I care. It's not as if these companies, all of them, Facebook very much included, aren't just bubble gas, top to bottom.
Twitter is all bubble gas too. The money is real, to the extent that money is real -- but the companies are jokes. The whole thing is based on doing to users what Yahoo is doing to Facebook.
Sell products and services to people, and then you have a right to get indignant when a sorry crippled hand-me-down like Yahoo turns into a patent troll.
