For the record --- in case any of Zymurgy's editors read this --- I like the "stretch" articles.
Obviously, some editorial discretion is required. There are a lot of adjacent fields that seem to be of overlapping interest to homebrewers --- culinary arts, history, horticulture, &c. --- but an article on, say, automotive maintenance or offensive strategy in football might be over-stretching it.
It would be interesting to see some polling data on what other hobbies homebrewers have.
