Accessible forms using WCAG2.0 from Web Usability. Code examples, screen grabs, video and transcripts of screen reader interpretations of forms. Very valuable. For educators: this is a great resource for an assignment. If I gave stars to my useful links, this one would get 5 stars.
Smashing Magazine is doing something interesting using Twitter. Their first post based on questions from forums/Twitter is Ask SM: CSS Quick-Question Edition. Questions posted to the SM forums or to @smashingmag or @chriscoyier are given complete answers in a column of the magazine. Common CSS problems are tackled in this post. I find this idea an example of “getting it.” A design magazine takes questions from readers/followers and answers them in SM’s well-illustrated fashion for all to see. This is a super example of a two-way street working well, of a magazine that gets what social media is all about. Looking for an example of a business that communicates in an effective way with its audience? This is one.
Compare what Smashing Magazine is doing with what Dell just did with it’s Della site. (SEE Big Aaargh! for Dell’s Della.) That’s an example of doing it wrong.
