I was always curious about this and Hammando's post on frequented galleries has prompted me to ask. I always love to hear what other's have to say about my gallery or my cels, whether from an update or just in general. With most galleries that I often visit I always email or send the owner some sort of note that I enjoy viewing their gallery and collection. Every time I do so, I always get a wonderful response, collectors always love hearing comments about their hard earned addiction. Part of what makes collecting so much fun is the appreciation.
Now I don't have a huge collection of gems in my possession, but I am still surprised in how little of feedback I receive.
I only hear from other collectors if it's for a offer or trade. I was just wondering what you guys do. How often do you contact a collector to simply tell them how much you admire their gallery? And be honest!! RS galleries make it ridiculously easy, just a simple click of a link where as an owner with their own gallery and host there's more work (well, not really), but maybe it's too much for a lazy viewer to do? To search for an email, and maybe sometimes not finding one? Do RS galleries receive more feedbacks than those with their own galleries/hosts? And when I say feedback, I'm not just talking offers/trades-- I'm sure plenty of people here are overloaded with those.
Just my little brain at work while I'm bored.
and of course I did. 
Early on in my collecting, I would mostly write people to compliment them and hit them up to sell one or a few of their cels. You bet - Now I like to write people if I see a new gallery I like - or if they're not a member of Beta so I can't compliment them in a post.
