I think that Waula is a very powerful social software. It is different from Google docs, Facebook  and any other social software we use before. When I login into Waula, it opens another windows like our computers' hard drive. There are a lot of folders in this new window. We can also join the other group to share our file and get the file sharing by the other people.

  I think the appropriate moment to use the Waula is to store big files to let people to download. Waula's advantage is just like the using the FTP server, but it is more convenient to share the file and to leave a message on the file. However, it doesn't have the file browser like Google doc, and photo viewing, photo tag, and the other small game like Facebook.  It means that if Waula want to be different and successful in the future, I think it should enhance the function of file handling in order to add differentiation from the other social software, or it is hard to attract users to use it like Facebook and Google docs.
