Interesting, Carl. I'd not even noticed that they were announced here in the past (but I just confirmed that the last few were). Since I notice them on the portal, I'd just not really noticed whether they were here or not. Clearly you do.
As for it not being here, I'd suspect it's just a slip on Saurav's part (since he had indeed done the past few), rather than an intentional change. He may or may not see this discussion, so I will email him to ask him about it.
