Hey jfarmer, thanks for checking out the site. That looks like a bug - you should automatically be following them if you used Facebook. We'll look into it right away.
I didn't connect with Facebook because I know all the dirty tricks people play. ;)
I can't connect now, after the fact. There are also some simple design oversights. For example, any time I see a list of people, there should be a "follow" button next to their name.
It's actually quite hard to find people to follow starting from nothing, unless I want to follow some of the 8-10 people you suggest automatically.
