Ethan Marcotte is a name you should be familiar with. If you’re not yet, and you’re a web designer or developer – it’s time you look him up…! Ethan was the one who coined the term “Responsive Web Design” a few years back (wow, time flies!). He has since started a web site which now has a wealth of information and interesting posts (unstoppablerobotninja.com), as well as written a book called – yup, you guessed it! “Responsive Web Design” (which you can find on abookapart.com) . If you have heard of him, but haven’t had a chance to look at his site or book yet please do. It will only benefit you. I promise. His twitter account however is much more – er, shall we say – profane. So only follow him on twitter if you’re not easily offended.
