I probably jumped the gun in my blog post. This is something we chatted about internally. Although we didn't discuss the exact frequency of these releases.
In general, we definitely want early feedback. However, we also want to get to a place that feels like a reasonable stopping place. A place where we can get feedback about our implementation, and not about errors that we are already aware of. Good to know there is interest in this though!
Also, on the subject of getting 4.0 feedback, we have something planned very soon that will help with this. Look for it in the next couple of weeks.
