From what I see, the user base is dwindling fast. My two cents... What the ecosystem needs most is two things:
1. An up to date to the default WebKit browser, so existing webOS devices can make the most of online browser based applications and sites and extend the life of TouchPad.
2. Ensure Open webOS can be easily ported to Nexus (or whatever mainstream cheap tablet device) to increase the end user base and grow a following from the roots up.
I'm not a ******, but webOS is a great mobile operating system. Specifically multi tasking, and it's the best for making the most of the devices battery life. Compared to Android, it still feels much more polished. (I get a "Linux" vibe from using Android sometimes... it just doesn't look like everything belongs together).
I think HP really under estimated how good webOS was/is.
