Having made the commitment to use the Omega theme and Delta module, of course the Context module is the place to start when creating a new website. I've come to think of Context as a replacement for the Drupal Core Blocks system. Previously, when I wanted a block to show up on one page, but not one or two others, I had to create settings for the block's visibility to "Show block on specific pages ~ All pages except those listed" and then list the individual pages that I did not want the block to appear. If there was some kind of taxonomy or URL pattern that could be discerned, then I could use that, but mostly it came down to listing the individual page exceptions. The biggest problem with that was when you created a new page, you might forget to add that page to the list of exceptions.
