My reports from Peru will mostly be in English, because the audience is more international than it is with my usual blogging topics (which mostly center on Politics, Switzerland and some technology). So for all people who don't understand German, it might be nice to be able to exclude all my blog posts which are not related. There are two ways for doing this.
First, you can just look at http://weblog.patrice.ch/en/. This includes all English posts on my weblog. The according feed (for your RSS reader) is http://weblog.patrice.ch/en/atom.
The second way is to just look at the Peru category which is available at http://weblog.patrice.ch/Peru. The category's feed is http://weblog.patrice.ch/Peru/atom.
Of course the latter solution will also work if you are interested in just one of any of the other categories.
