The document The Path to Raku includes this:
Sites such as PerlMonks appear to be really Perl (aka Perl 5) focused, and could possible make that clear in their description, or change their description to specifically include Raku.
Although it's true that most of the nodes posted on PM are about Perl 5, several of the gods have made it clear on several occasions that Perl 6 / Raku posts are welcome. So this node is just to point out that references to "Raku" should probably be included in the PerlMonks description, although I'm not yet sure what the best way to do so is.
Also, I'm not sure if it's feasible to go back and change existing posts, but perhaps we should standardize a [raku] tag for post titles.
