As Discussed at the last «meetup» in Bern we could read Ethan Marcottes «Responsive Web Design» (A book apart) and then discuss any questions, disagreements etc...
This would be awesome if we could hold this Meetup in Bern as we would like to get a regular thing going here as well.
Weyert proposed an alternative book: http://www.implementingresponsivedesign.com/
You are free to choose, which one suits you more.
People who don't manage to read the book in time, are also welcome as always.
