In my opinion, Alice is the Google Guru that I love. If I have a "How to Do something Google question.... her site is where I go first. I also follow her on Twitter and she tweets GREAT stuff! You can also follow her blog, which is a wealth of very useful Google and practical hints, tips, and ideas.

Eric Curts is another one of my go to Tech and Google experts that I rely on to keep current.

Matt Miller is definitely one of my favorite people to follow and learn from. Check out his ideas, thinking, and shared resources here!
