Are public Beta sites closed only for numerical reasons. I saw Is there a list of failed/closed betas? and the highest upvoted answer actually points to a google search which is primarily due to numerical reasons and as far as I could search this google search points to no results.
Is there a process for closing a public beta for reasons like
- The beta has perceived "low quality" content
- The beta is moving in a direction that was not the direction it was originally envisaged to go
- The public beta in the form it exists would be a duplicate of other sites on SE (which wasn't originally envisaged)
