Some good advice... personally I tend to "curate" follows pretty tightly... unless I feel someone actually adds value to what I am doing or one of my areas of interest, I don't care. I just don't get into the whole "ego-popularity contest" thing... what's cool about that is that I can toss out a piece of content to my somewhat limited (relatively speaking) following... and get 1000+ actual reads as a thank you, often prompting "how do you DO that???" comments from peers who have 300,000 on twitter or wherever... quality over quantity, any day!
