Emily--
You should cache articles from sites like the New York Times website so that everyone can read them without creating an account and continue to read the article after the two week (or whatever) period expires and a subscription is required.

Caching involves saving the content of a website and linking to the saved version rather than linking to the original site where the data is likely to change. You can do this by simply copying it and pasting it into the blog, or by using a free online caching service. Depending on your preference, there is a commercial version (http://www.furl.net) or you can use my own personal website (http://www.adelweb.net/websave/).
