Here are the numbers for the number of job advertisements posted to jobs.perl.org in 2008, by month. I'm not affiliated with jobs.perl.org, and this is only the simplest of analyses. I didn't try to correct for duplicate posts where the same job was re-advertised. I don't attempt to draw any conclusions about the popularity (up or down) of Perl from these numbers. In general, I think that the continual uptrend through 2006 is about more people discovering the service, and the dismal numbers in 2008 mostly reflect the current economic cycle more than anything to do with technology.
