Absolutely correct - it is my personal opinion. It's things like personal opinions that keep the conversation going.
But when it comes to personal opinions that predict the future success of a corporation you're not employed by, or seems to make decisions for them, I think that kind of opinion should be kept to oneself, regardless if you think it "keeps the conversation going". That doesn't sound like a good conversation.
I'm not against the posting of opinions, just this kind of opinion.
