Personally, I’m looking to make something a bit more accessible and fun.
I have a hip pocket full of business fails caused by poor UX design, either physical or online, and was contemplating putting together something on the five biggest UX disasters.
I’d also recently read an article about 14 Uncomfortable Habits That Will Make You a Better UX Designer. While I’m not in a position to try all 14 (#2 suggests quitting your job with nothing else lined up, which isn’t really practical with a family that depends on me), I had also considered putting together something where I do one each day over a 2-week stretch and discussing the results.
