I began with a show four years ago when I think I was looking for tips on grip-shift shifters and bart had the best how to. (Now Park Tool has very detailed how tos). You missed his dad Mr Pump who acted as a foil who would berate Bart and ask him what he was doing. After Mr Pump passed on, Bart became the alpha male. Different vibe but still good and acceptable. All the other 'shows' are just biking videos, like GMBH, etc (see my list of what I check out). They aren't live which makes all the difference.
