To me the post sounded as if the poster was suggesting they're were no other cool development tools that were on-par with Cappuccino, thus we should all mourn if they stopped developing. The poster if you recall was not a Cappuccino developer.
It's in my opinion, and I'm sure in many others, that there are many other cool development tools, some of which are on-par, if not better in various ways than Cappuccino, many of which don't get the attention or appreciation they should get.
