The owner of this dominion is also the same person as these users at the given external domains:
Everything2 (e2, c. 2000-14) was the first "social network" experience for me, Wikipedia was next (2006-16), and my contributions to the latter venue are public.
2017-02-01 I cleaned out all FB accounts I could, think I got them all ¹. Did same for Google+ some time before, used mainly for the Hookups conferencing.
My interest in external venues is as provider of labor supporting them rather than as a participant.
GitHubEtc has more external links.
¹ At that time I created an account strictly for development purposes.
² In general as software, FB, Google maps, other SaaS with separable free API are the exceptions, CMSes aren't.
