I had no idea how user friendly Facebook is: notes re friends in common, suggested friends, regular e-mails regarding responses related to anything I've posted on, alerts re responses to friendship requests.
I'm moving slowly, in an organic fashion. I began with friends from the CommanderBond forum, which I frequented for years. Then I tried approaching writers whom I used to know years ago, but fell out of touch with. With a couple of exceptions, all friendship requests have been accepted...resulting in more suggested friends.
Today I checked out an agent, Don Maass, whom I've known for a long time. Don confirms in his Profile that he uses Facebook to check out writers' Facebook pages. So I'll continue to fine-tune my own Profile page. And I sent a friendship request to Don.
Progress report: 21 confirmed friends, 5 requests still out there.
Next step: get a good picture to post there. Don Maass has raised the bar with his own photos. Try to match and raise the bar.
