This is Palm's chance
Palm needs to start courting developers again. They have a state of the art mobile operating system, a very open API, an excellent set of tools and terms of use that don't dictate how apps can be developed. All of that makes for a fun development environment.
Palm hasn't sold as many devices as apple or android so they won't attract as many developers who are writing apps for profit, but what they will attract are hackers and tinkerers and creative types who like to push and poke and see what happens when they do xyz. I think that in itself will attract higher quality apps and that will be key: quality not quantity.
As a user, would I really care that your platform has 150000 apps and mine has only 2200? No. As long as the major apps are there (which they are for webOS) it doesn't really matter.
Palm should stop trying to be Apple and start being Palm again
