If you know of any sites that you think are particularly good examples of the issues discussed in this section, please send their URLs to the group, along with some comments on why you think that site is so good.

Discussions of pitfalls to avoid are also permitted, but I'd rather you include those only when you can make constructive suggestions, particularly with worked-out examples of how to implement your suggestions. I happen to think that there are plenty-enough bad examples out there for people to stumble across, and I'd rather focus our energies on identifying and praising good models for others to follow!
