Web apps are used all the time in every day lives even though the user may not be realizing that. Web apps are used more like tools then as games to make our lives easier even though they can sometimes be complicated to the average user. Some web apps are more popular then others because they are more useful while others seem to almost be completely pointless. I personally love web apps and use them frequently compared to the average person. I really like "oh don't forget" and "Google Docs" is also pretty cool. "Aviary" is not the best unless you really enjoy doing that kind of stuff.
