I'm by no means an expert on the subject, but i did find when starting out with a straight and experimenting with different types early on that wedges were a more comfortable shave for me. Maybe the heft of the metal counteracts the typical inclination to apply too much pressure. Or the added thickness changes the way you perceive the angle you're shaving whereas a beginner with a full hollow might use too small an angle. Either way, I'd say that anything you read on a blog is subjective material and not to be taken as fact.
