Much discussion happens on #perl6, our IRC channel. This is the fastest way to get help.
Another way to stay tuned is reading posts from blogs that focus on Perl 6.
You can learn some basics about Perl 6 with these introductory screencasts by Gabor Szabo. Gabor also frequents our IRC channel.
Perl 6 is well represented on Rosetta Code, where you can see Perl 6 (and many other languages) applied to numerous programming tasks.
For more persistent discussions (and for the poor folks who can't use IRC) we have several mailing lists.
As of 2014, the lists have very low traffic (because most activity is on #perl6), but every question sent to it usually gets answered swiftly by at least one person.
You can subscribe to each list by sending an email to email@example.com.
