Well, in order to try to make life a bit simpler and add a bit of order to this chaotic world of blogging… i decided to start using categories (as WordPress calls them — tag is the name everyone else uses) based on the arXivs (as you can see in the posts below).
So, if you want, you can look for something like this… and, if more people start adopting this standard… maybe we’ll really be able to organize posts that deal with material from the arXivs in a comprehensive way. 😉
Have fun… ’s! 🙂
