In all cases where doubt crops up, ask yourself, "If I had a gun to my head and had to do it, how would I do it?" It's not as hard as you think.

The least-crowded channel for meeting high profile bloggers is in person. Email is the most difficult, the most crowded... I'm a top 1,000 blogger, not a top 100 blogger, and I get hundreds of pitches by email every week. Most of them I don't even see because my assistant declines them.
