For me, I think Baytor hit it out the park with number 1. I'm still relatively toe-dipping with comics, and I feel that relative value for money helps. I like that the walking dead comics would do this (albeit while still doing the weekly issue or so) for every story arc or thereabouts. It helped give more of a natural rhythm to what I was reading.
I think, for me anyway, there's that much choice out there its almost intimidating as to what to go for in terms of picking up something new, or dipping into something old. Its like introducing someone who knows nothing about beer to a gigantic bottle shop full of all the good stuff. They won't know what they want.
