I should have qualified my last post with, "If you click on a profile on a competitors site it will show you who they are friends with whether you are friends with them or not." Obviously someone can look at their Friends list on SLS to see who they are friends with, but that's a specific page that someone has to go to for that purpose. When's the last time anyone looked at their Friends page just because?
As mentioned, nobody sees your Favorites but you, and the suggestion was to somehow make it known that someone Favorited you. That would be kind of like the "Like" or "Flirt" on some competitors sites, and many just see that as lazy. I can see one possible exception.
There are profiles of couples I view that I like but will not reach out to them if our weekends are already booked a month out in advance. I never think to use Favorites for that, but I suppose that was the intent. I do make use of Profile Notes though.
Any date out more than a couple weeks I've found isn't likely to happen. We put it in our calendar but, more often than not, others do not. When the date comes close and we touch base, it's about 50/50 that they forgot and made other plans for the same day. We also prefer parties over 2 on 2's, and some parties don't get scheduled much farther out than a couple weeks.
