With the seemingly crazy premium placed on 9.8 vs even 9.6, I can see why the default for many people is to just press any book they submit. I doubt it pays off nearly as much as all of those people think it does, so being much more selective and actually learning to grade a bit is probably more lucrative in the long run; whether you are doing it to improve your own personal collection or flip or whatever.
But yeah, on facebook (and the modern section here seems way too much like facebook sometimes) the mentality is that if it looks like a comic book, better press it just to be sure. And slab everything, no matter what. Slab slab slab, press press press, twenty dolla grails 4lyfe..
wait, sorry. got off on a tangent there.
