Casa Azteca is another of my favorite Mesoamerica-related sites. It is quite a thorough and up-to-date source of news and commentary, especially on archeaological subjects. As a bonus, Casa Azteca lists upcoming events in different sites around the country. In general I’m not that fond of Live Journal as a platform; nonetheless, but Casa Azteca is one of the premier sites for information about Mesoamerica and the Maya world.
