If everyone who posts a layout decides to "give back" by then commenting on say 3 layouts, then the Gallery will become more vibrant a space and more inspirational for all. Maybe if everyone is looking at other posts more often, not just from their friends or teammates, they might find inspiration in an unlikely place...
There used to be a "Five a Day" thread encouraging people to comment on 5 layouts a day and to post that you have in the thread (thus bumping it and reminding others) Five might seem a bit arduous especially if there aren't many recent uploads, but three sounds good!
