Thanks - nice site!  Ben Reeves recently noted that it answered my '“Market capitalization” over time'  question at stackexchange: http://bitcoin.stackexchange.com/q/2047/99

But as I noted there I'm puzzled as to why the "unix time" timestamps for the daily data points in the json output aren't for midnight UTC.  Why always 14:55:45 UTC for the market cap page, and 18:15:05 for transaction-fees, etc?

Also, for http://blockchain.info/charts/transaction-fees can you stop rounding off the fees to the nearest BTC?  It's just bouncing around near zero now.

And do you know why there is a huge increase in estimated transaction volume since Nov 16th, to all-time highs?

Finally, can you put in a redirect from the original URL for the site (http://pi.uk.com/bitcoin/...), so old examples posted here work?
