RWD Weekly #400

Hello and welcome to the 400th edition of Responsive Design Weekly. Firstly, a huge thank you to you for being part of the 400 week journey. Every week it is an honour to be in the position to hit your mailbox and share the things that I’ve read and learned for the week, and even more so when you hit reply to request updates, suggest other articles, or to just say a quick thanks.

There’s no change to the newsletter for the 400th edition, but I can share that we will be reintroducing the interview series for the month of April and we’ve got a number of previous interviewee’s and some new faces as well… very exciting stuff.

For now though, let’s get linking.
