An interesting and fun read is the relatively new blog What's Up El Salvador?. It's written by Nanelle, who along with her husband Andy have relocated from the US to El Salvador. From the blog's description:

Living life in El Salvador as American expats and loving it.The blog is full of wide-ranging posts about life in El Salvador, as seen from the eyes of a family of newcomers. Nanelle updates the site very regularly and her writing style is breezy and fun. It's now one of my regular stops. Check it out.
