Flâneur in English is via French from the Old Norse verb flana “to wander with no purpose”. Flânerie then is indeed core business for the Order of Walkers and this post is merely a highlight of this historical french practise as written on wikipedia. I suspect the clandestine “Wander Society” would also draw upon its principles.
Flânerie is the act of strolling, with all of its accompanying associations.
Appraise yourself with the practise.
