Appcelerator, a company focused on cross-platform development tools, has started extending itself into the world of APIs by offering mobile developers drop-in tools for integrating their applications with popular web services. Appcelerator recently announced a new offering called Titanium+Plus, a set of premium modules that developers can purchase to incorporate into applications built using Titanium Mobile, Appcelerator's open source mobile development platform. Rather than mainly providing new or deeper access to the core functions of devices, the new Titanium+Plus modules are focused outward—or maybe upward—towards the cloud. In fact, the announcement came with a new tagline: "The cloud starts here™".
