I actually wouldn't mind seeing an interview with K9 or Liquid C, both are players I'm rather fond of. Another from DN would be Face Mine Wrath, and from BD, Pinky Toe. Lethal Touch (aco.Mne) of THE would be a great interview. For Hammer, maybe their leader Supaphat or McMellow (both interesting people). Cececole or Duchess of Devonshire from Decide would be interesting to see. I would say yourself Paj, but since that's out, I'd have to go with Mick from your tribe, as he seems pretty vocal, and probably offering a distinct perspective of the world. Contrary to what Netjakdim said, I'd like to see him interviewed. I recognize him from other worlds, and he seems like pretty interesting fellow. Likewise, that Lord Brutii guy from NADS seems like someone worth checking out. From Green (Plague?), I would either interview their new leader, to give them a chance to touch on their new tribe and its fresh image, or perhaps Spidey.
All of these suggestions are for people I have seen on the PnP, that actually come on here even if only rarely, but all are vocal, opinionated, and seem to have a unique perspective on things. Some of them are high profile, but they are something to consider. I will post mroe as they occur to me.
