The trouble is I'm having great difficulty connecting this to code changes.
FOAF went in in September.
There are a bunch of important bug fixes in December.
We experimented with reducing request latency, and implemented turtling, in 
January.
Nothing at all happened in March.
DB4O was merged in April.
0.7.5 was released in June.
Caching changes in end of July, but it's a limited sample anyway, give it time 
to settle imho.

PROBEALL: actually seems to be working and producing consistent results without 
steep jumps. It shows 2229 nodes when I ran it recently. This is an estimate 
for the number of online nodes at a given time. Last time I ran it much, maybe 
a year ago, it consistently showed around 1000 - although for a while it had 
big jumps i.e. was grossly inaccurate (presumably due to backoff problems). If 
we assume the figure of 1000 is reasonably accurate then the network has 
doubled in size and performance has improved considerably.

However, the other side of this - we have 22K downloads over the last month, 
that's 700 per day! And the number of nodes online at a time is only 2200. So 
we still have massive churn. :(

Also the uninstall survey has dried up, there are very few responses now, too 
few to be useful. Maybe we should always show it if opennet was enabled? Or 
would even that be too much?
