I thought about your question, etrader, and something I think you could do (somebody please correct me if I'm off base!) is write a targeted local article on your topic and then write one or two evergreen articles to link to from it. So for example you could write that Tuesday is National Lava Lamp Day, and highlight some things in your city that are celebrating, with links, how-tos etc. Then you could write an evergreen article or two about the Lava Lamp, and assuming you were a business writer, you would write about their business practices or how their stocks have performed, or whatever. I would post the evergreen articles first, and then post the local article with links to the evergreen articles. Then you have two relevant articles to read, but one is current and the others are evergreen. Every subsequent year you could link to the evergreen article.
