I read it several different ways.
Pressed for time, I use google reader and flip through the backlog rather fast. When not way behind, I check each one, again through google reader, and manage on weekends to often clear the queue.
I also check the postings and comments of several of my favorites to see if they have spotted anything interesting that i have missed. I do this when my time is even more limited.
If I am able to drain the queue, I check "ask" or "comments".
And of course check "threads" to see if there are any replies to my comments.
I seldom visit the home page. It seems that whenever I do, I have already seen at least the title.
It might be a bad sign that I have such a thorough multi-pronged approach.
