I've been having a think about running some vox pop exercises for student journalists I'm working with, so I've been trawling for some ideas and material.
  Unsurprisingly Wannabehacks have some thoughts from their own experience.
  They also have some tips and comments on how to get perfect vox pops.
  There's even a guide to vox pops on e-how plus some general interviewing tips from journalism.co.uk. 
  Among the various examples of the craft are the regional daily reporter who carried out vox pops in her pyjamas after Tesco banned PJ wearers from a local store.
  And Newsphobia gets upset about Twitter being used as a lazy journalist's replacement for vox pops.
