Full of great little articles on everything from usability to typography, A List Apart has even started to produce its own series of e-books.
Do you hate those salesy 'newsletter' emails as much as we do? Well here's one we actually signed up for! Jakob Nielsen is a usability expert (although web designers either love him or hate him) and his occasional emails are packed with thought-provoking stuff. His site also carries a series of insightful articles on the subject of UI/UX which are free to access…and are a coffee break well spent in our view.
Okay, perhaps we're verging on the nerdy here, but these guys really know their typography and aren't afraid to share their excitement with you.
