I've started the recent DailyUI project. It's the first time I've done something like this.

My daily work is for homeowners and tradesmen, quite a specific audience. Almost all our design decision have some data behind it — whether it be qualitative or quantitative — so I understand that a UI challenge might some somewhat devoid of constraints.

I know the challenge is for my own benefit so I try and think of scenarios and edge cases that differ from my day to day when I approach task. I try and think of additional potential constraints and explore concepts that I found difficult before.

Most importantly I've taken to finding other people's submissions and providing feedback, usually something good and something not so good. I invite others to do the same. I plan on posting these on my blog when I get a chance along with an analysis of my own submissions (I'll link it when it's ready).
