Perl did show back up in the TIOBE rankings as #10 and then #9 (Perl5). There are plenty of blog posts and conferences...just not as much as Python, Java, C#...etc. Perl6 is starting to get checked out by the first wave of people who like to dive into new tech, so a bunch of blog posts have been showing up recently.
Perl6 is fascnating! And there arent a lot of 'woah' new languages about (Rust, Go, elixir, D, elm, nim, clojure, typescript, are all 'old hat' now...) so for people wanting to learn & play, perl(6) offers a lot of fun.
perl5 is certainly dying (but still strong on legacy). development stalled for 20 years.
perl6 is doing the worse-is-better approach, by focusing on all thinkable features (sans structural matching and proper destructuring), but with a performance making it unsuitable for production.
there are some perl11 projects (5+6): cperl and rperl which solve both problems. suitable for production, proper performance and proper features.
