At the time of writing, blockchain.info reports the latest block as 248603.  blockexplorer.com reports the latest block as 247902, which is 701 blocks behind (nearly five days behind).

The reason I ask, is because I think that two Android applications I'm using to view Bitcoin wallets are using blockexplorer.com:
"Bitcoin Wallet Balance" by Phase Industries
"BitCare" by Cryptcoins Software Foundation

I received my first payout as a bitcoin miner, and I thought that it hadn't come through because both of these applications show the balance as 0.  Checking on blockchain.info shows the correct (non-zero) balance.

(I wanted a Bitcoin Wallet that could display my balance as a widget on the screen (without having to enter the application), and "Bitcoin Wallet Balance" does that.)
