perl.jobs summary for 2012

Every year I count the number of jobs posted to jobs.perl.org (and sometime last year I put it all in github). I make no hard interpretation of these numbers and don't take them to mean anything. I think the rise in numbers up to 2006 are merely from people finding out about the service. I have no thoughts on the decline after that.

jobs.perl.org provides its own counts. I don't know how it's counting, but its data doesn't fit what I see from the postings. For instance, in January 2013 it counts 111 jobs but there were only 101 posts in that period. I also suspect that it's counting duplicates. I asked about this last year without an answer.

The 210 uncounted messages are people posting directly to the list, spam, and other non-job postings.

I only count the first instance of a posting by looking at it's URL. According to the nntp archive, many jobs have repeated posts. I don't know if these are for the same seat or the same position with multiple seats:

I wrote the stats code for jobs.perl.org a million years ago. It's broken for reasons I don't exactly remember. It's something about the way the job posting date is changed when a job is updated, I think.
