The problem with buses is always not enough buses. If a bus came every 5 minutes you wouldn't need to spread out the stops as they would naturally spread out with fewer people getting on/off due to more busses. It would make transfers more tolerable, missing a bus wouldn't matter, buses wouldn't get packed around rush-hour, etc. Buses could be a great public transportation system but I don't think any city cares enough about public transportation to properly fund it. It's easier to pass single, large funding bill for some light-rail boondoggle than it is to continuously fund a working solution.
