Every time I write a new Hub, I post the link on my Facebook page, as well as on the pages of some groups I belong to and some friends who are "fans" of my work. Which amounts to maybe a half dozen times, in total.
Occasionally if I can't come up with something witty to put in my status update on a given day, I'll post a link that goes directly to my Hubpages profile strictly for the heck of it, usually with a self deprecating joke like "I can't think of anything to status about so here's a link to my articles on Hubpages. Have you read a Hub today? You'll laugh, you'll cry, it'll become a part of you."
