I strongly disagree with this. While it is complicated in Ben's case, we had 
GPG signing party at the past Akademy and we can rebuild the web of trust. 
Debian works like this. We can have one at the QtCon (with also people from 
other communities including FSFE). So *signing* the announcement emails should 
not be discouraged like it is in this email.
