Comparison of Social Networking Sites - Green Day

By looking at these three sites next to each other, I can clearly see a few similarities across them:

• The same imagery (avatar) is used to represent the band.
• This imagery often advertises what the band is trying to sell.
• Anything important (such as a new music video) is announced on all sites.
• Fans can interact personally and are encouraged to do so.
• The band doesn't respond on a personal level to their fans.
