I made a google spreadsheet with the number of transactions occurring in the bitcoin block chain per month, and the total value of those transactions:

(click on the BitcoinTransactions spreadsheet; the first is just another version of #produced over time)

Looks like bitcoin is growing nicely; I'm not sure why the big spikes in July and October...

I made the calculations using my bitcointools python code:
