I keep seeing post flagged as "woo" when the information isn't woo at all. Woo is not saying, "yeah, this is awesome information or great job." It's saying, "this is potentially dangerous and/or misleading information." It can also mean that the information posted is a myth that has been debunked. Telling someone to use a food scale to make sure they are accurately logging is not woo.
Just throwing that out there b/c there's a particular topic on here where every helpful post from people is getting hit with woo. I'm going to assume it's b/c people don't know what it means within the realm of MFP's forum.
