Uh, you missed one critical point (Score 1)

As per Google Webmaster Central:

"Similarly, we only retrieve GET forms and avoid forms that require any kind of user information. For example, we omit any forms that have a password input or that use terms commonly associated with personal information such as logins, userids, contacts, etc. We are also mindful of the impact we can have on web sites and limit ourselves to a very small number of fetches for a given site."

Stuff like login forms, contact forms or forms for user generated content should be using the POST method not GET, so there shouldn't be any concern for web developers who know how to design their sites. If you are using GET in the wrong places, then it is your own fault.

What is the motto of this story, read the actual post/article in detail before overreacting on something posted out of context by a slashdotter. (and yes I'm also guilty of this)
