Part of the big Google announcement from the other week was a better and smarter knowledge graph.
I noticed this a few days ago, that when you search for anyone or anything that returns a knowledge graph box on the right side, you will now see an additional option to "Get updates about X" and a button that says "Keep Me Updated".

I am hoping I get to see what happens on Google Glass or Google Now when this comes up in the web search results as a new story.
Same with a search for [matt cutts]:
I already have alerts set up for Matt Cutts, so maybe they will be similar? Have you seen the Google Now cards for these types of subscriptions?
When you search for musicians, you will get a slightly different option to keep track of releases.
