Just as an example, let's say a school teacher uses her computer for email, web browsing, managing files, photo editing, and maintaining her second grade web site. Gmail, (some browser), dropbox, snipshot, and splashup/weebly would be all she needs.

If all these websites were somehow organized in a way that said teacher can easily find them, then I think a 'startup revolution' would be more likely: people could go to a central website to browse for startup that meets their needs.
