We're now listed at the bottom of the first page when you search for
proxomitron! (can anyone else confirm?)

That is correct (in google.com) and the only way is up

For those listing 100 results per page, it's actually very close to the 'top' (no. 9 excluding nested results).

i'm also showing it as #9 (#10 if you count nested results)...
i only show 25 results per page...
