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.

Windows: Microsoft’s Fix it Center is a beta troubleshooting program that tweaks common Windows issues—sort of like previously mentioned FixWin—but it comes straight from Microsoft. It’s average-Joe friendly, and addresses everything from network glitches to media player issues.

Fix it Center is still in beta, but is stable enough to use. The program offers a variety of categories (27, to be exact), and will give you an estimate of how long each problem will take to troubleshoot. Once you select a category, the program will take you through each situation step-by-step. The instructions are easy and clear to understand, with an easy intuitive interface.

Microsoft Fix it Center is a free beta program for Windows only. It supports Windows 7, Vista, and XP. If you’ve tried similar troubleshooting or tweaking applications, let us know how Microsoft Fix it Center stands up against the competition in the comments.

Windows: If you’re setting up a new system or helping a friend to see how much great free and open source software exists, ZeuAPP is a portable installation tool for nearly a hundred applications.

ZeuAPP is essentially an installation dashboard for 82 applications. You can navigate to application types like CD Burners, P2P apps, Office apps, and more. Under each tab are applications for that category with a “Download” and “Visit Website” button which allow you to download the application and automatically launch the installer or visit the web site for more info.

ZeuAPP is freeware, portable, and Windows only.
