The priority is building out the product and that is exactly what they are doing. So stop crying about new exchanges. They will come sooner or later. If you can't wait then sell and move on.
product development, it's good! But they said there will be only 5 exchanges! And most of them will not be very good, for example such as Hitbtc!
They only promised 5 exchanges in the official business plan/white paper, but they are actively working to get listed with many exchanges right now. They are not permitted to release the details of those negotiations before the exchange does.
The community is currently working with them in attempts to gets listed on several exchanges at this time.
I personally doubt that it will be much longer before Hive is on several additional exchanges.
