When I started digging deeper into Thematic, I tried searching for just a simple picture of where the thematic widgets were located. Since I had no success in finding it, I have provided screen shots that I personally created and used for those of you who may be searching for just a simple visual explanation.
Now that I have it memorized. I feel like helping other newbs like myself out. It would be totally awesome to leave a comment if you found this post helpful.
Another site you may find useful that displays thematic widget areas and hooks is Visualizing Thematic 4 You.
