At which point can facebook start suing around for [slander/damages]? It's not like they did all this in secrecy , they were quite open about their platform with developers (which has helped developers warm up to a company that basically sells gossip). They never will of course, because they 'd be retroactively judged with today's standards. E.g. I find their unfair advantaging of the Obama campaigns a lot more troubling than this.
