when are we do for another difficulty change? 
On Saturday afternoon most probably.Network hashrate dropped significantly today and average between blocks is back up to 9.5 minutes or so. I guess I would be surprised if the diff went up on Sat, but what do I know.
You have a good analytical mind - don't put yourself down,

Of course now the network hashrate is climbing again (it was 140,000 GH/s earlier and now 160,000 GH/s) and time between blocks is down to almost 8.5 minutes. I am curious about the large fluctuations in the total network hashrate. I mean 20,000 GH/s is the size of Slush's entire pool, how does that much compute power come and go so quickly? Its like someone with 40 BFL Mini Rigs is dropping in and out of the network. If I was in charge of $900,000 worth of equipment that generates sooo much that a few seconds down can cost $1000s or $10,000s of dollars, I would make sure as
#!&| that the systems didnt go down.
there was talk on another thread that ASICminer was turning large numbers of rigs off and on
My internet picked a good time to puke out on me. It went down 3 minutes before we found the block. I wonder what I can get for 0.00000006 bitcoins?
