I have been doing a little housekeeping on the site. There are a few changes that I think are worth mentioning. They are all related to some new content that you can access on the top of the webpage.
You have fast and easy access to a lot of very interesting links if you click on very useful as well as on Direcciones Interesantes related to search engines, web 2.0, GNU/Linux, free software, etc. Let me be clear, these resources are done for my students for academic purposes but I think it is very useful to have them freely available for everyone at anytime.
Please, let me know what you think about that, how you would improve it, etc. Your comments encourage me 
and help me to keep going.
