I’m not sure how I feel about this.
First note: I don’t use Yahoo!, except on the occasion that some blog post leads me to Yahoo! News.
Second note: I do, obviously, use Facebook, but I’m not what you would call a fan of the site.
Either way, I’m uncertain about the idea of such targeted advertising. Indeed, when using the “Login with Facebook” feature at various websites, I take a moment to make certain I’m not littering my timeline with a bunch of automatic notifications. And because of the way Facebook likes to tell everyone what its users are doing, I generally don’t respond to invitations to play various games, or enter my birthday on a calendar, and so on.
To the other, it’s Facebook, so … yeah. I kind of knew what I was getting into when I signed up for an account.
But I would prefer my social networking to network according to my wishes. I do not accept the proposition that my friends, or the world in general, need to know everything I’m doing online.
