The year is 2013. It's a post-webOS world.
HP has sold off the webOS group, and the buyer has stripped it for the patents, and shut down all the infrastructure needed to support webOS devices.
The HP App Catalog and the Palm Profile servers can no longer be reached.
The @palm and @webOSdev twitter accounts no longer respond. The developer forums are a barren wasteland.
Some people take the easy way out, and simply move to another platform.
Others learn how to survive, using ... The webOS Survival Kit
(Yes, The webOS Survival Kit is the link to the wiki page which you should follow and read now.)
If you have other tips for survival in a post-webOS world, please post them here or edit the wiki page directly to include them.
