Very much appreciated this post in the midst of the hype of this coin. I've played a bit with the wallets and functionally it's great to see XRB moving so fast without fees. I also changed my representative to a random one further down the list and this made me wonder how the default representative is selected. I think this is key to the security of the network and the team should expand on this in the whitepaper or elsewhere. Another issue is I self-representation which seems to be possible. If many wallets do this they become dead-end-streets when offline and all balances eventually routed to these will not be able to assert their voting power which reduces decentralization.
