This is a pretty awful "announcement". It doesn't tell you what Openbeta is or why I should care. I had to click through to a link to find out whether I cared about it or not (and I don't).
Hire a better press release person, Betaworks.
What is it about?
> Openbeta from Betaworks (a new medium company)
This looks like a placeholder for a company/productname/tagline. Could not be any more bland.
