Sure. Why give tips to people who won't be here in a year or two?
Gotta start recruiting fresh blood !!
Those who come into it chasing 'hot books' are joining this hobby for the wrong reasons. In general. Maybe they'll gain a real appreciation of the art form eventually, but... that's again, generally, NOT what I've seen.
I like the people who come into my shop that are 'digital' READERS, attracted to the hobby through the storytelling and art (an aspect that's fully from digital), I think they have a better chance of sticking around. No matter how bad some things get... there's always something else worth reading...
Chasing hot books... will only lead to disappointment for most.
If they are digital readers what are they up to in your store?
