We've been working away quietly on the next feature patch for Discover and this time took a bit of a chance with a new feature. This one was a long shot but investing in the development days to prototype was the only way to know for sure, and we wanted to try.
Long story short, it didn't pan out and we've pulled the feature from the upcoming feature patch but it's not Dodo dead so it's back in the secret features list waiting for us to take another run at it.
If I could wrap this up in a lesson, I'd quote Homer Simpson - "Trying is the first step towards failure", except failure is not a bad thing, it's the tuition we pay to learn, get better, and do better.
