I like the idea that Tom would put together various blends for the weekly roast, revealing all the contents from existing green stock so you have a chance to sample the well roasted blend and have the greens in stock to make your own. A couple other benifits are to spread ideas on how blends are put together and get home roasters more comfortable with blending. Roasting the components of a blend separately is the best approach and allows the most roast flexibility.
....I think the best way to learn about blending is by tasting/drinking Single Origins. Only once you are very familiar with the variety of SO, notice and understand the differences, blending starts to make sense.
The first question about blending is: Why blend at all?
