Perl developers and LinkedIN

At the end of April 2012 I collected some data on the number of members of the Google+ and Facebook pages of Perl projects.

I left out LinkedIN but as Gautam Dey also mentioned, it would be interesting to see the numbers there too.

There are several other Perl Monger groups there with less than 60 members. Sorry, I got tired manually looking up and copying this data.

Conclusion?

I think there is a very big overlap among these groups. If I wanted to guess, I'd say the total number of people in any of these groups is around 12,000.
