2) On btcwisdom, for Coinbase, it says 'volume disabled', but tradeblock.com/markets/base/xbt-usd/ seems to be able to get the volume data for Coinbase. Could you maybe take a look at it to see if you can get the same data? I think Coinbase will become pretty important among the USD exchanges over the coming months.
I believe it is still showing the old brokerage service, not the new exchange.
That's plausible. 
Just noticed that Coinbase, the exchange, actually now makes their 24h volume public directly on site (i.e. without being logged in). Don't think they did this from day 1, but this probably means there is a volume feed of the exchange now.
Would be great to have an updated 'coinbase' market on bitcoinwisdom
