I can't tell you how many times I've read a post or a reply and I go to click "like"...LOL! I rarely have something new to add, and I hate to reply just to say "I agree"...a Like button would be really handy!
I've actually had this same thought the last couple weeks. Its where I don't want to necessarily reply, but definitely would like to have a like button on it.
