Dunno - Ron and Luna would make interesting teachers.
Like the idea of Harry being DADA teacher since he did such a good job of DA. I can't see him working at the ministry either.
Hermione would be another option but I'm not sure she has the patience to teach. I think she'll be doin more with S.P.E.W etc anyway.
Ron will probably be doing more hands on work. Hold on, I'm getting carried away - they might not all survive!
