I liked Tim's
graph
of bloglines readers so I copied him.
I don't think this is so much a proxy for readership as it
is a proxy for the growth of
Bloglines itself.
See below for
a graph of my readers over the same time period;
my general readership curve is pretty steady, nothing like the knee
in the Bloglines graph.
I'm counting unique readers by IP address; not perfect, but
close enough.
Python makes doing things like this such a joy.
Here's my hack code.
Ugly, but simple.
Update: the big jump in February Bloglines seems to
be correlated with when I
turned on full RSS.
