Well I did contact Diatonic about this last week, he said he was overrun but would try to manage it at some point. He did update, but his blockchain is still wrong...

If there are any volunteers for setting up an alternative block explorer, it'd be great.

Considering CoinChoose and most coin choosers, they actually base their data off the block explorer, explaining why they are not in sync with us. But as you said, it might be better that way until the coin gains more hash power.
