Exactly, these apps need to implement the gossip model and relay hints need to be more ubiquitous; the solution is not making the data more widely available by syncing between relays or by using something like blastr.

Like I mentioned last night: this is largely not the case and we still have a lot of work to do.

Providing gossip-type behavior is the whole reason of being of NDK, because the path of least resistant for micro apps is to just connect to two or three big relays and be done with it.
