There are right now quite a few promising technologies out there. Nobody can possibly learn about them all, so I have to choose. Here are the technologies to which I'm commited to learn more:

• Ruby and Ruby on Rails: I recently performed a series of experiments (Spanish) and was very impressed by how well thought Ruby on Rails is. I cant' wait to see Rails 1.2 released to be able to try Active Resourse, which I see as another great step forward to the raise of REST.
• REST: I initially thought REST was just a simpler alternative to web services based on SOAP and WSDL. It's much more, it's about how following a small number of well thought rules web services can be much elegant and simpler.
• Microformats: are a way to embed semantic data within web pages. For example whenever you insert a date you could use the hCal microfomat to state that it is a date. That will make it consumable not only to persons but also to those person's tools which could offer him to add the date to their Agenda. There are already many interesting microformats and their main streght is how easy it is for web authors to include them.
• Edubuntu: free educative software for schools and (in the future) for universities.

I will be blogging about them all in this website.
