Sam Gentile is back. My recommendation: ignore the e-mail from nay-sayers. In the long run, those that do the most are respected the most.
I get e-mail all the time from people telling me that something I am doing is wrong. Amusingly enough, most contain unsolicited suggestions as to what I must do. Those that seem sincere and come from people who appear capable, I try to encourage them to participate, which generally results in an answer that they are too busy.
The rest, I simply treat as spam.
