What's to update? His bio says "has been". It doesn't say "is".
I must say that while I very much appreciate virtually everything you post, I cannot fathom why you bothered to even look into Johnson's background. I don't believe his bio, other than references to positions held recently/currently (at PTSC), has changed in years. It just strikes me as strange.... No biggie though, as it turns out, just some wasted post space - something we have plenty of here.
