No.
A block explorer should make for interesting reading if it includes the transaction messages.
I think standard block explorer software should work with FLO with little effort. It won't display the messages though. For transactions without messages, the standard version 1 transaction blocks are used. For transactions with a message, version 2 transaction blocks are created. The block explorer will have to be modified to understand those version 2 blocks.
If someone feels like attempting this, I'll throw in a 200 FLO bounty (I know, it's not a lot).
