Yahoo (s YHOO), after a rotten week, might actually get some positive press! The company is launching Yahoo Mail as a platform tomorrow and organizing a big shin-dig in San Francisco for the launch. Last week, I had reported that Yahoo would launch this platform relatively soon. The company has been getting a few applications ready for the launch, and I know of at least five apps that are part of this launch. In response to my previous post, folks left links to blog posts and other bits of information that give a clear outline of Yahoo’s plans.
