Neither “social media,” nor the software-writing that makes it happen, is particularly mysterious to the penitents this Monastery.   I guess what I am looking-for in your thread is ... “what is your point, and what is your call-to-action?”   PM is a very special-purpose site, concerning a specific programming language (and the sort of programming that is commonly done with it, which is a lot of things).   How is it not accomplishing its mission now?   How would the addition of “social media links” or what-not, enable the site to accomplish its present mission better?   I don’t see it.

PM is a best-of-breed resource for the Perl community.   It is also an excellent place to get insights from brilliant people concerning the sort of tough problems that Perl is routinely called-upon to address.   (A few of those people obviously hate my guts, but they’re brilliant, anyway ...)   Sure, it might look old and crusty, but, “looks are not what locomotives are for.”   PM is essential to the Perl language’s success, IMHO.

Please make a case for exactly what you think the problem is, why we should address it, and exactly how we should do it.   Get specific.   And, always focus on the mission of the site.   Make a business case for what you have in mind.
