Microsoft Office Web Apps on SkyDrive and Office 365 are finally catching up with Google Drive. In a blog post on Wednesday, Microsoft’s Amanda Lefebvre announced that real-time co-author editing is now possible on Office Web Apps, including Word, Excel and PowerPoint. The number of potential collaborators that can be working on the same document in Word and Excel is limitless, but there is a 20 co-author limit for PowerPoint presentations.

All of the features that come along with co-author editing are included in the Web Apps, such as a list of teammates and their location in the document at the top right of the screen and a colored indicator that follows each teammate’s movements and keystrokes. Word, Excel and PowerPoint also received individual functionality updates. Microsoft’s Web Apps are beginning to look like a serious option for collaborative editing.
