Occasionally, if I'm on their userpage and something catches my eye.

I dont tend to browse another persons favourites as much as I do their Gallery however If the deviant or group has a favourite on display that catches my attention, sometimes it makes me curious to browse through the rest of their favs. hence why I do at times.

I totally check out other people's favorites. It usually makes me feel guilty for not having very many favorites of my own to share. I should get on that.

I browse peoples favorites rather frequently. If someone favorites my work I will browse their favorites to see what other art they like as well. If I like an artists work I will browse their favorites to see what kind of art they like. It's very interesting to see the different collections people have and make, and what types of art people like etc. Very fascinating stuff for sure!

Yes.

I've found a lot of great artists that way!

Not all of the time, but I've noticed that if I'm on the page of an Emoticonist or someone who creates a lot of character based work then I'll have a look through their favs/collections to see if I can find any new artists to watch and be inspired by.

Yes because I'm an art collector. So if I like their art, I'll usually like what they like.

Not unless I'm looking for DD suggestions.

If I find a talented deviant, I am interested not only in their art, but also in what they like and what inspires them

And, occasionaly, they watch people I don't watch and are in groups I am not in… so, it's a nice way of finding great art. Or possible DD features
