You probably use this resource, Greg, but for the readers who ask you about new physics developments and such related to your writing. Also, perhaps Terran could make a sort of sticky(ies) (or maybe a FAQ) for things like this, and for particular posts you've answered that may seem like potential returners.

Thanks for the link, Patrick!
Thanks for the suggestion, Patrick - I didn't see an RSS feed for that site (maybe I just missed it?) but I've added a link to the site itself on the "Science News" page (see link at the bottom of this page).
I like the idea of flagging certain discussion threads, too - I'll look into that.
