I just finished listening to a great podcast (as usual) from Peter Clayton of Total Picture Radio with Shally Steckerl, the guru of LinkedIn gurus.
The cast, called LinkedIn, Reloaded, explores some of the new additional features of LinkedIn since their last redesign. Clayton queries Steckerl about how and why you should connect to people, how to leverage your network in your jobsearching, and compares LinkedIn and other social networks such as plaxo, naymz, ecademy, facebook and one I had not heard of, xing.
One interesting question Shally takes a stab at in a very good way:
How openly do you accept network connections, and why?
