Well said:

And released software — particularly released software that is available for sale — is open for criticism.

In what way does Disco, or any other app that is labeled “beta” but is available for sale to the public, deserve to be cut any critical slack?

I've ranted elsewhere about this sort of thing -- where the genre tells us that criticism is not acceptable in that forum -- but let's at least admit that we, the audience, are/is getting snowed, even if the snowing doens't work.

The "beta" action, especially the pay-to-play beta of MS's office recently, is absolutely out of control. (Speaking of, is Furthurnet.org ever coming out of beta?!)
