For the record...
I don't consider lack of a specific response to one of my posts a "snub." Nor should my not responding be considered a "snub."
Sometimes a post stands pretty well on its own, and there's little to add. Sometimes it's too much work to construct a useful response. Sometimes the subject has run down. Sometimes I miss a post.
And sometimes it's best to stop before this twitchy software starts screwing up a long thread.
