I'd kill-file him, if he wasn't such a seductive target for supercilious observations. -- Bill Sloman, Sydney

The S/N ratio is about 1000:1.NT has the same problem as Tom Del Rosso - you have to be able to process the signal before you can distinguish it from noise. -- Bill Sloman, Sydney

Rich Grise dropped off the grid awhile back too--he was sometimes fun, and certainly added to the local colour. Who else?

I thought the worst. Maybe he'll rise again. Then there was Danger Dave who apparently knew he was dying, and didn't say so AFAIK, but he did post a witty short story told first-person "from death row" on his last April Fools Day. https://groups.google.com/forum/#!original/sci.electronics.design/jVMvv1JnNb4/8bL-KX_I_zAJ

Life is short.And NT's cognitive resources are pretty thinly spread. So much to be gullible about and so few opportunities to demonstrate that gullibility. -- Bill Sloman, Sydney
