If you are a regular reader, you will remember the Frappr map I started on Friday to find out where all the CF is in the world. Well, since then some 500 flags have been placed on the map telling us a fair bit about the community.
1) We now know that there are at least 400 developers out there who read blogs/aggregators regulary (i.e every 24 hours). I personally would guess at more than triple that after taking into account non-click throughs and people who didn't add a tag. Additionally, I have noticed that Sean Corfield's and Ray Camden's blogs are amongst the most-read blogs.
2) CF is mainly prevalent in the US (east beats west by some margin), the UK (south v. north) and Austrailia.
3) Around 7-8% of CF developers are female.
4) Frappr is incresingly slow and unreliable.
