You can't read yourself into social adeptness. I'd suggest participating in some non-nerd social gatherings. Figure out something you like and go spend some time doing it. Oddly enough, the nerds you do meet in other contexts tend to be interesting and well connected. (In Berlin for instance, there's a large overlap between the open source / founders social scenes and the electronic music scenes. I met my cofounder and many of the contacts that we're using through music rather than, say, the local LUG.)
