Sometimes when browsing the site I stumble across a very sweet, all-around nice profile of someone not in my area. There would be no point in me messaging them (I always assume women get ton of spam on any type of matching site) but it would be nice to send them an anonymous Like - a simple "you're appreciated" button.
No public "Likes" counter or anything competitive like that, but a little something only they can see such as "12 people appreciated you this week" would be a nice feature for when people check their account.
Or maybe something like that is already in the mobile site but I'm overlooking it?
