I also hope that they are thinking a bit more strategically that asking people for suggestions... Strikes me that there are some obvious routes that need to be filled in.
Leith Walk clearly needs to several hire points, heading out to join up with the lone Leith hire point.
Once that's done, then the Portobello dock is very lonely, so that triangle needs to be filled with docks.
Personally, I would love to see then extend out along the canal, obvious spots for hiring next to the new Boroughmuir School and University Housing, and Fountain Park, then either end of Harrison Park, Meggetland, I'm not sure where I would then put stations, but possibly at or near the other parks, but certainly near the Hi-rises, Westside Plaza and the WHEC - joining up with a bunch of stations around Edinburgh Park and the Gyle.
Also as others have pointed out Lothin Road, Haymarket and Dalry/Gorgie could very easily be linked into the city center, and this applies to just about the whole city.
If there are around 150 bikes out at the moment betweeen 25 stations, that's 6 bikes per stations, If the target is 1000 bikes at that ratio that's 160 stations, which significantly increases the area covered...
