Why do we have a thread advertising the alpha release of software? Besides the fact that it's not really newsworthy, I think suggesting new users try the alpha is a terrible way to introduce them to software. If I download Opera 10 Alpha and have the same problems that AG did, I'll think, "Damn, Opera sucks!" Obviously, that's not the case--the latest stable release works just fine. So you're advertising an alpha release to the wrong people--the general public rather than developers and debuggers.
Further, I'd submit that if a developer is interested enough in the status of Opera, she probably doesn't need advertisements for its status--she will track its progress on her own. In short, this thread is targeting the wrong audience, and the right audience has no need of this thread at all.
