[Air-L] Looking at job postings: Any advice?

Hi everyone, I have been following everybody's answer to Devin's question about Graduate programs for "internet studies" and I have found them very interesting from a PhD student perspective as well. So let me ask you all the following question: What would be your advice for a PhD candidate starting to look at job postings for next year? How can I find a position that fits or should I jump at any opportunity? How can I distinguish myself? What are universities looking for in general? Thank you all in advance, Christine
