My comments from a discussion thread at the private forum for expat entrepreneurs run by Karen Armstrong: You can find me on Facebook (which I'm using increasingly more as a place to share what I'm reading, thinking, what I'm doing, etc -- and created recently an Expat Harem page which still needs a lot more love), Linked-In (which I've begun to join in forum discussions here and there) and Twitter.

I'm most active on Twitter because it works so well for me as a writer, as an expat, as a trafficker of ideas.

With Twitter I'm back in school (taking business courses, marketing and media affairs), I'm at summer camp, I've rejoined the publishing industry, and making new filmmaker friends, and following peripheral interests through the lives of people more devoted, taking part in live discussions about literature, editing, branding, virtually attending conferences and events like yesterday's brown bag luncheon thrown by Random House on the topic of digital publishing.

The other two sites have their purposes but nothing touches Twitter.
