I'm not opposed to generate a second key, but I don't really understand
how it solves the isolation issue. I'm not used to key signing parties
and am presently in the situation where I don't know whom to ping to
sign my key. The only thing I could do was to sign it with my old key
as you suggested in the initial mail on the subject :-/

So if at least generating a second key can save that hassle for next
time, I'm all in favor of making it, it just takes a few seconds.

Best regards,
Willy
