I've had co-workers that never wrote POD, and that was probably the worst. But the next worst are the people that inline their POD. I really cannot stand inline POD. Apparently I am not alone. Mike Friedman expresses it at least as well as I can so I'll leave it at that.

Well, almost. He says one odd thing:

  If someone's looking at your code, it's because they need more information 
  than the documentation or interface itself can provide.

I don't think this is even half true. I often look at Perl code that has perfectly good (and non-inline) POD. Almost always because I'm less interested in the public interface than I am interested in how that interface was written. What fun is software development if all you do is work with the public interface of blackbox libraries? It's much more interesting to see what's going on behind the scenes and actually learn something new, right?
