DC renumbers and goes digital - Do you care?

Not sure how I feel about the DCU comics being rebooted and started over. This has been happening way too much the past five years, with 52, Infinite Crisis, Blackest Night/Brightest Day and now Flashpoint. Why should I care about characters that may be completely different in a few years.

I'm curious if folks agree with me about the effect of digital comics on shops. Also, how many digital comics will be downloaded. You can't resell these and you certainly can't get them graded. I'll stick with comics on paper for now and just not bother with DC. Not that I'm their target audience.
