One “little” feature makes Google Docs superior to Zoho Writer, and that is the file tagging. I have been using the Zoho online word processor for a while but after some months my list of files was becoming huge. Then, I noticed that Zoho Writer does not have folders or any other way of sorting the files. The only feature they have is the search, which alone does not always help.

Then I came back to Google Docs and I love it. You only have to mark the file and select the folder where you would like to put it. Another plus is that you can put the file in many folders as you wish, working actually like a tagging system. For example, your meeting_results file could be in your meetings folder and in your specific project folder as well.
This tagging system is often referred as “folksonomy”, with which users can tag and manually specify attributes to files making the search and retrieval much easier. This is even more useful in social and collaborative environments, where the more [relevant] tags the creator of the file use, the more easy will be for the one searching for the document to find it. A good example of this is del.icio.us, where the people tag bookmark links with several tags.
This kind of solution is really straight forward and it is really a pity that a OS like Windows does not provide such a way of organizing files.
Once again, thank you Google!
