Agreed mate, some fans a too quick to turn as we've seen. Personally I'm not expecting the current relatively good times to last for ever, but it'd be nice to think that we might at least get a few years stability and genuine progress after years of shite and let-down. Other clubs seem to manage it, why not us?
That said, I think key to success is good leadership, consistency and focus from the top down, I don't think there's a great deal of difference between fans of different clubs when it comes down to patience, especially if expectations have been raised for whatever reason. We've only got to look across at the Sty with seemingly everything going for them financially right now, but without a pot to piss in just a few years ago, to see how quickly fans can forget the crap they were in and and turn.
