What prompted me in making the comment is that the title suggests your post is about troll hugging. But in describing that whole story, you do some large side-stepping, that in my mind are not related to the subject that you gave the post.
I'll take the Judo/Aikido paragraph as an example, in an attempt to form relations between that self-plugging paragraph and the concept "troll hugging" in your mind.
The Judo meme was first introduced to me by mjd in "Conference Presentation Judo" ( http://perl.plover.com/yak/presentation/ ) -- and because Larry Wall and Damian Conway both practices Aikido, they sometime use those two memes interchangeably.
I was reflecting why I've always refrained from using Judo/Aikido to describe what we've been doing in #perl6.
During writing that blog post, it occurred to me that it's about the destination; Judo/Aikido tries to contain and then throw out incoming attacks by making the attacker lose balance, while what we've been doing is quite the opposite; it aims to restore a conversational, one would even say hermeneutic, balance.
So by writing out that paragraph I feel I understand the "My Hobby" part a bit better, whilst also trying to explain that reflection to people who joined in the aikido/judo meme circle before.
That is how the relation was formed in my mind. Hope it helps!
I missed the reference to the xkcd meme upon first reading (my bad! can't believe I missed that :( ) and upon rereading this does make it a lot more focused.
Just noted that you were new here, or at least, the account was. Enjoy your stay!
Gosh, I felt ancient in internet-time, and it's so nice to be a newbie in various communities again. :-)
