The QT81 is a terrible route. How many people from Whitestone would actually benefit from a bus connecting to Astoria? Chances are, most people are getting off or on at Flushing to go in one direction (either to/from Astoria, or to/from Whitestone). The worst part is, once there is traffic on one end of the route an entirely different group of people will suffer from it, going against what they set out to do...
Not to mention the new routes in Bayside are going to screw certain people over, with the lack of weekend and off-peak service. I don't understand what function the QT71 serves, as it connects to no subway stops at all.
Generally, from how I see it, the way they re-did Northeast Queens was quite sloppy, connecting corridors that might not have much to relate to each other. I really think the number one thing should have been connecting people with the subway at all times, and with these new purple routes that are peak hours only, I think it might make things worse for a lot of people.
