That said, a non-tech person I sometimes send some of those articles to was asking me if I knew of or how to find sites that have some of the same traits - high quality submissions, an active audience - for other areas.
For instance - history, cooking, or plants might be very general areas. It seems like Reddit is a popular spot for such. But any thoughts on discovering high-content sites in other, non-tech, areas?
Owing to the lack of an HN-type site in these areas (that I know of), I rely heavily on RSS feeds from all of those and kind of "roll my own" HN.
