Exclusion

The last two posts reminded me of Seth Godin's recent post on exclusion (that I still haven't decided if I agree with), and my own experience as a co-op student. While I'm sure the idea of avoiding exclusion is generally practical from a general marketing perspective, I wonder what Seth Godin would have to say about hiring co-op students?

Clarification: for most companies that consider hiring students, there is a certain expectation that there can be high turnover and in this light, many professional services firm view the hiring of co-ops and the expense of training them as part of marketing to future buyers of their services. Can the feeling of rejection of those who you don't hire really be avoided?
