Depending on your e-mail settings, it’s nice to be able to “like” a post to show your support, without then receiving 50 e-mails that say “so and so also commented on your friend’s post,” which is what happens when I leave a comment (no I don’t want to change my settings!).

I would agree about the potential danger of “liking” a link for the reasons you mention. Finding an article interesting and agreeing with its premise or argument are very different!
