Meta bloguing

I changed a couple of things on the blog template. If anybody reads this with an aggregator and all previous posts appear as updated please let me know.
I added a new section on the right bar were I plan to keep some previous post that might be interesting to discuss. I had this change in mind after reading this post in Notes from the Biomass about blogging. It is true that blogging platforms don't make it easy to revisit ideas. I'll try to find other ways to do this.

I also updated the blogroll with some links. Neil's blog and Yakafokon on bioinformatics, some tech blogs I particularly like and a the blog of a portuguese friend of mine.
