The real success of the day was in the UK where we climbed first to #5 then to #3 then #2 and finally #1 where now remain. The reporting tool seems to be playing catch up - we've had a few thousand reported downloads, but it's still ticking up in bursts as if it's collating data from other servers. We'll let you know how many downloads the #1 position actually represents as soon as we can.
We're now starting day 3 in approx 40 minutes as of the time we're writing this, and our download total is well in excess of 20,000 copies shifted.
Our biggest 'ad' of the day was being featured by the Frugal Ereader, and we've now been featured by all the big sites except Ereader News Today (but hey, there's always tomorrow!).
