i wholeheartedly agree - and you pointing that out has just shown that it is a really interesting observation/view. I had never put huge amounts of thought into it, versus other cities. One of the unique properties of Edinburghs Transport being effected by its geography.
By geography i was more referring to it being a more dense city particularly around the centre whereas Glasgow is more spread out, however that is an interesting point you raise. Of course there is also the blatantly obvious difference that Glasgow is built to be very car-centric, so naturally more people will drive rather than using public transport regardless of how good (or not) the service is.
The way Edinburgh is built and its roads are set out it's far more favourable to bus route corridors. It's somewhat hard to explain but basically at times of lower bus usage it's easier to maintain a higher level of service as you can run one fairly direct and frequent service along a corridor rather than various less direct infrequent routes, whereas with Glasgow (except maybe to the north west of the city centre) it's not as easy to do that as if you did you would leave large areas unserved. I guess it mostly stems from the fact that although Glasgow does have a main city centre there are various "town hubs" around the city that almost act as their own separate city centre entirely.
I'm not really a huge fan of comparing different public transport networks, especially when there's so many variables that can play a part and you have two cities as vastly different as Edinburgh and Glasgow. Although there's no doubt that Lothian's offering is far above that of the Glasgow operators a good bus network/operator doesn't necessarily mean higher bus usage or greater profitability, yes it's a factor but it's not the only factor. There's other influences such as public transport integration, bus priority measures, traffic levels, geography, population demographics, costs of city centre parking and good partnerships with local authorities just to name a few which can all have a big impact.
Sorry if that came off as a bit of a rant, but i thought it would be worth while going in to a bit more detail.
