I don't want a competitor to LinkedIn. I want a next-generation replacement for LinkedIn. One that doesn't spam me. One that doesn't encourage others to spam me. Xing looks nice, but it is very focused on Germany and german-speaking countries in Europe. But they are kind enough to have a landing page in English -- well-written, English, too. I'd almost use them for that reason alone, even though I don't speak German and I'm not in Europe. I can't tell anything about step.com, which seems to be in beta and focused on NYC. Surely the YC/HN crowd can come up with something good, right?
