As excited as some of us still are about Google Wave, Wave’s biggest problem remains: “What would I use it for?” With the app’s new wave templates, Google wants to guide you toward answers.

Now when you visit Wave, the New Wave panel (and the new wave button) offer options for starting waves using templates for common use cases. Gina and I highlighted some of our favorite, creative Wave use cases over at The Complete Guide to Google Wave, but the new templates offer a really helpful jumping off point for collaborating in Wave for common uses, like discussions, task tracking, meeting notes, document creation, and brainstorming. You can still stick with the default blank wave, but it’s seems like a step in the right direction to help new users get familiar with the tool.

Microsoft and Facebook just launched Docs.com, a document creation and sharing web site that integrates with Microsoft Office and Facebook.

You log into Docs using your Facebook account. Once there, you can view shared documents. The service is currently in a fairly early beta stage, meaning you’ll have to sign up for their waiting list before you can upload or create your own documents. Because of that, there’s not much to the service now, but it’s clearly a push toward competing with Google Docs.
