My Conversations to catch any replies, then My Users to catch what's new.
I go through Conversation first as many people I converse with are commenting with an answer or advice and not just a comment if you see what I mean. Then I go to Users second, so I don't miss any of my friend's new posts. I used to love using My Interests as I have often found a new person had created a post that wouldn't necessarily have been front page and I wouldn't have seen them otherwise. I like to welcome them to Soulcast too as newbies. Once we subscribe to each other then I get them in My Users. My Interests is now almost out of bounds for me as an Adult Content tag user as it's now filled with about 15 pages of 'you know who' as he uses Adult Content tag :-(
I must admit that I am easiy sidetracked so flit on and off the feature pages all higgledy piggledy :-)
