Here are some resources I’ve found very useful from Doug Hennig for the past few months;0)
TIP: Compressing Virtual PC images: Craig’s tips are always great and this one saves lots of disk space.
Why Your Business Must Be on the First Page of Google: yes, it’s marketing, but since we’re all involved in marketing one way or another, you might as well figure out how to do it better. Mike’s blog has lots of useful tips and I found this article really interesting.
Evolve Your User Interface To Educate Your Users: the Smashing Magazine blog is mostly web-oriented but is almost always interesting. However, the ideas in this post are also applicable to making desktop apps easier to use.
I also think many people will find Eric Hebert’s “The 50 Most Popular Web Design Blog Posts, Resources & Cheat Sheets of 2007” very helpful
