I do try to submit good stories to the pipe

Thanks. We need 'em.

not duplicating /. or SN if possible.

I've never been concerned about that. While I'd never want to copy /. or SN stories, we certainly don't want this community to be left-out just because somebody else mentioned the topic first (poorly). Furthermore, I've found it very interesting to compare how the different sister sites cover the same stories (when that occasionally happens), with Pipedot always having a vastly more accurate and in-depth write-up.
