Bits of usenet are acting flaky at the moment (the servers, I mean--we all know about the posters).
For Rick's "comparator with wide CM range" thread, Supernews and Google have 25 posts at the moment, but the thread is completely missing from eternal-september.org and aioe.org.
My "cute dpot hack" thread has 21 posts on supernews and GG, vs.
5 on ES and AIOE.Cheers
