You have now the official definition of snake oil, but in my experience what it often means is a knee jerk reaction against something that fall out of common acceptance, and then too often becomes mere insult.

Witness here how certain posters seem determined to trash the product. No matter what the defenders say, they simply must come back with something, and they will keep going until the defenders simply give up. Notice each attempt subtly shifting the goal posts each time the defending argument is put.

Do I want to post examples? Absolutely no. All that will do is end up the same way. No matter what I say, there will be endless comebacks until people get annoyed with the whole thing ending up in a similar cycle. I'll leave it as one of those things a read can decide for themselves.

So be careful, the use of the term snake oil can tell you as much about the person using the term as it can the target.
