Now this is the kind of challenge that I think people in the design / weblog crossover community should seriously consider undertaking more often. 37signals decide to design a usable online banking experience. Seems to me that there’s an interesting project – develop a site where people can develop their own, and comment on other people’s, interfaces for many of the sites that we see around the net all the time – e-mail / calendar / banking / e-commerce etc. The feedback that people could develop between each other could actually lead to more intelligent intuitive interfaces – and if they were developed as open source or concept, then the whole net might benefit. Interested?
