I think this taking the wrong lesson from Netscape. If you do a greenfield re-write of a multi-million line application you probably are going to have a bad time, but people successfully re-write smaller applications or portions of an application all the time. Since this was just a portion of the total functionality of LinkedIn, they incurred much less risk than a ground up rewrite would have.
