I like viewing pictures of what I like to shoot. Take barns, there are a ton of barn groups in Flickr. Barn groups can be as broad (barn) or narrow (red barn) as you like. Posting to a group (barns) you see photos you can fav or comment on which may or may not lead to group members doing the same to you. A good picture is a good picture no matter the resolution, I like that if I have (IMO) a good shot I can post at a higher resolution than Nites.
