Me thinks beginners have enough to worry about without adding continuous binding to the list.
You really only need bias binding if there are curves on the quilt edge or a striped fabric you want to highlight.
I just looked quickly at five (pretty recently published) quilt books sitting in a reachable pile (on the floor), and none of them suggest doing the binding that way.
Otherwise, one can do a killer binding using straight cuts of fabrics.
I cut my straight binding 2-1/4" (as do most people I know).
I don't really think it's a big problem.
