If I just added a new category of posts, like I did, the problem would still be the 90% of portuguese posts getting in the way of people who don’t speak the language. Not only that, but since I use feedburner I lost access to WordPress’ rss versatility for categories, post authors and any other combination you might imagine.
The answer came from Yahoo Pipes.
What I did was set up an alternative RSS feed for posts written in English. Yahoo pipes retrieves my feed, blocks any content that doesn’t match the “en” category and feedburner picks it up again.
So here you have it, enjoy and please feel free to give me some feedback if you use it.
