Adrian, I like your analogy. I'll throw in another... When I first learnt to drive I was happy to drive any car and enjoyed the freedom. Now I prefer driving a decent car, enjoying the driving experience and aspire to occasionally/eventually drive a great car. As for what is going on under the bonnet, I haven't really got a clue, but I have a few amateur opinions about tyres maybe, or what paint finish looks best?
As for the Belfry, several years ago, I'd have agreed with you that most people outside of this site would think it great architecture, but I've come across so many people recently who don't like it, that I'm more with Sean on this one.
Cheers,
James
