I like a lot of "crap" on FB that means absolutely nothing to me. I "like" a lot of stupid crap that people post there as well. I "like" a lot of stuff the I have never seen, experienced, bought, used, etc. It doesn't necessarily mean that I "recommend" it. "Likes" in general, I think are very, very weak recommondations at best.
However, my "Like" for "Woman with Sexy Tatoos" stands! ;)
