I like to spend time looking at the new uploads page (browse -> latest). You tend to find some good people to follow that way. I also search for places I'm interested in and find people that way too.
Happy to follow you- the best way to insure I leave a comment on your shots is to follow me and comment on mine. When time is of the essence my method is to reply to your comment and then use your icon to go to your latest shot to leave a comment on yours. Welcome to 365!
