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.
| Project/Site | |
| Bugzilla | 263 |
| CPAN Developers | 558 |
| Padre, the Perl IDE | 50 |
| The Perl Foundation (TPF) | 704 |
| YAPC::NA | 52 |
| Perl | 10,042 |
| Perl Jobs | 2,990 |
| Perl Mongers | 7.085 |
| Advanced Perl Users (JAPH) | 315 |
| Perl Jobs UK | 185 |
| Perl Mongers | |
| Perl Mongers India | 267 |
| Israeli Perl Mongers | 183 |
| Boston Perl Mongers | 113 |
| St. Luis Perl Mongers | 99 |
| Los Angeles Perl Mongers | 81 |
| San Francisco Perl Mongers | 77 |
| Atlanta Perl Mongers | 67 |
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.
