Is bad grammar becoming the accepted norm?

I read this post today by the very successful agent, Kristen Nelson (who is on my dream list of agents) about 50 Shades of Gray and what books like it are doing to the publishing industry....basically books that are poorly written, but by some fluke are getting mega attention.

The comment made by the very first person really made me think. (I didn't go on to read many more comments, as I had a feeling I might walk away from this post feeling crabby and I really didn't want to puts myself in a bad mood!)

Anyway, if you don't want to go read it, the commenter basically said that the average reader doesn't care about style and grammar, only editors and agents do.

This really made me start to wonder. Have readers just become used to poorly written books with bad grammar and stories with shallow plot lines?

Part of me says no. I also read recently that readers have become extremely leery of the 99 cent book...they've been burned far too many times. It's only a buck, but still....once you buy 10 or 20 bad 99 cent books, it sure adds up.

As always, this industry just keeps changing and morphing. Where would I be without Twitter to constantly update me??? LOL!
