If you are the owner of a blog that incorporates any slow loading widget then you have probably experienced the seemingly unavoidable effects: the post section loads first, but the background of the post section or sidebar doesn't fill in until everything in your blog's sidebar finishes loading.

I began experiencing this difficulty myself after I added several widgets to my blog's sidebar.
Fortunately I have now developed a technique which eliminates this formerly unpleasant effect. I wrote a tutorial at:
