how can we get honey traded on other exchanges
It will be hard to motivate exchanges to add honey since there isn't much trading activity right now. Even on coinexchange there is only $400 USD in honey/btc trading today. This probably adds up to maybe a few dollars in fees.
After we see dev's big announcement this might change.
Yeah that is the problem right now for Honey, the trading volume. However I think it will pick up once like you said we get the big announcement from the dev which I think we be in the next week or so. Then once the volume picks up we could try and get Honey listed on more exchanges. Its a shame that when Nova exchange comes back that they won't be having Honey listed on there any more as they have delisted Honey already, not sure why as they still have a lot of dead coins listed on there but they delist Honey, doesn't make sense to me. Maybe once everything is in place we could try and get Honey relisted on Nova once again.
