Here you can get the App:
http://apps.microsoft.com/windows/en-us/app/e900af2c-d352-4d51-87d5-d48bb46db079
This is a simplistic app for filtering out MSDN blogs (not just single blog posts) that are in foreign languages that you cannot understand, or blogs which cover topics that are not of interest for you.
My next steps are to internationalize the app, and let it to show a longer history of blog posts.
I developed this app initially for myself but figured that others might find it also useful. I would be happy if you try the app and give me feedback.
