This may be "preaching to the choir", but it never ceases to amaze me that there are still development/technical leads that are not reading at least a few blogs regularly. I've gotten into the habit of reading by blogs daily, and this has resulted in so many benefits. The shear number of tools and techniques I've found because of the technical blogs out there I can no longer number. It's like having hundreds of team members all doing research and development and reporting on their findings. It has gotten to the point where I almost no longer peruse web sites with technical content - the information just flows to my RSS reader.
If you're not reading blogs regularly, START NOW! Omea Reader is a nice client-side RSS reader, and you can pick up a copy of my feed list on my public resource list.
