There's no more queue for instant, it's now "My List," but choosing it from the menus on top (it's listed under "Watch Instantly), will bring it up in one nice list, with a "notes" section to let you know when it'll be disappearing off instant. Likewise, if you have a DVD plan, going to the DVD queue will sometimes let you know if a title will become available for streaming in the next few weeks.
From a business standpoint, I can understand that. As a consumer, it's frustrating.
I'm even more frustrated, though, that they aren't revealing upcoming titles as they used to. Reddit usually seems to get wind of it first, but the sites you listed were good sources before they made the change.
If you're on Facebook, the Netflix Facebook page reveals titles once they are added (for instance, their page yesterday trumpeted the return of Mean Girls). Beware, though, that you'll also get their holiday themed postings and when one of their original programming (such as House of Cards) becomes available, they post on that several times throughout the month.
By far my favorite Trek series!
