From bitcoinwatch -- Bitcoins sent last 24h 3,368,696.34 BTC
Roughly half of all bitcoins in existence were transferred from here to there in the last day?
Or the same coin transferred three million times?
Volumes like this are a good thing. Bitcoin movement means trade. Even if we assume a very pessimistic 50% of transfers are from self-to-self; that would still be signs that the bitcoin economy is active.
