In your opinion, who is, and is it on a single digit list of people who are for you?

I don’t know what you’re trying to say here, but I’m going to guess you’re asking who is a reliable tech expert. So if that’s your question, here’s my answer:

For general hardware/server/enterprise stuff: Wendell from L1

Consumer hardware repair stuff: Louis Rossmann, although he’s been doing less of that for a bit

Linux stuff: anyone of the Jupiter Broadcasting hosts

BSD and ZFS: Allen Jude
