Here's a sterling example from the email I just received:
Each author will do one blog a week, and The Full Plate Diet staff will do two weekly blogs a week.Dang! Really?
Because I'll clue you in. "Meanwhile, Back in the Kitchen" is a blog. What you are reading right now is a "post." Amateur mistake. Which, if one is getting any sort of advice at all from informed sources, one would know. Forgivable in individuals, just plain clueless from a probably professional writer.
Also, having a disclaimer that one must agree to before one reads the blog? No. Period. If the info is that sensitive or likely to be misused then don't put it on a blog people. Far better to have an overall disclaimer as part of the main layout ... or at the bottom of each post. Or something like that. Pretentious.
So the overall effect out of the box? Clueless and pretentious. I hate that because the book has much worthwhile info and probably the blog does too.
Why did it annoy me enough to post about it? Just lucky I guess. I see these errors constantly from people and companies who I know were advised by professionals ... who aren't on top of their game. It irks me.
For examples of how to do it right, including disclaimers, check out the Quick and Dirty Tips gang, especially Nutrition Diva and House Call Doctor.
