Lots of people have asked lately if there is any secret listing of great blogs out there that would be good places to glean new ideas from... While there are lots out there, I find them too general and not focused on the exact area that I'm trying to research. What works well instead is to start at Technorati , search based on the topic and then hop across blog contacts that are listed on a site that you like.
Technorati does have an interesting Top 100 list though that has introduced me to some new blogs worth revisiting...
