Hi Mike,

I am glad you are still following up with Bitnodes. The recent spike in
nodes count should probably be taken with a grain of salt; run #231 (
http://getaddr.bitnodes.io/231/) does appear artificial to me, i.e.
potentially bogus nodes being added. I am still working on a more in depth
analysis on the data.

There are quite some TODOs for the project at the moment for the next
couple of months. I have included propagation data as well into the list.

Cheers,
Addy
