I agree with a lot of what you say, Greg, and I know you have your tongue in your cheek here (at least I think that's what the smiley signifies), but this attitude is one that I believe puts some people off taking up cycling. Would you say the same about car ownership - how many people even know how to open the bonnet of their car these days?
It's possible to enjoy cycling without a lot of technical knowledge, as I discovered when a guy I was riding with once said, 'What's all this about replacing chains anyway? They last for ever don't they?' It turned out he'd had the same chain on his crappy old mtb for 11 years and it was still going strong (I wouldn't like to guess how many miles he was doing a week though)! When he was finally persuaded to take the bike to be serviced he was most offended when they suggested it wasn't economical - most of us quietly thought they had a point. He's still very much enjoying riding it as far as I know.
My lbs have been very helpful and reasonable since I bought my road bike and I'm very happy with them - thank you Matt and George at Future Cycles in Lewes.
Somewhat. My local club includes, in the non sport sections - I don't ride with the fast boys and girl - a number of people who when faced with something as trivial as a puncture go into a sort of moral collapse. They stand staring at their bike in mute disbelief and are utterly incapable of fixing it. I can only assume they never, ever, ride alone when it makes sense. Couple of years back I came across a roadie on a carbon framed bit of expensive loveliness stranded on the roadside and phoning his missus to come get him because he couldn't pump his tyre up because his pump was a) shite and b) set up for car valves. Good job too as he had pinched the tube.
Most mtb-ers, and that's where I became a born again cyclist, and I suspect a good many frequent long-distance commuters, are self-reliant and well versed in the range of get-you-home repairs and bodges needed to see the journey to an end and avoid the long walk.
On another, related, point; I know of some really good LBS's and Future Cycles is on that list as it happens along with Corridori, Brixton Cycles, etc., but none of them are local to me. It must be me.
