Bubbletop is a new customizable start page that is similar to Pageflakes, Netvibes, yourminis and Schmedley. It will appeal to internet users who are active in social networks and so have a lot of online friends to keep up with.
Bubbletop is unique because it uses a friends system to share the content you find/use on Bubbletop. You can “friend” people on Bubbletop and then click the share button and after selecting your friends, they will get a notification of new content from you. Of course, the catch is that your friends must be using Bubbletop as well.
Another cool thing is that Bubbletop lets you take widgets from other providers and use them. For example, you can take a widget from yourminis and bring it into Bubbletop.
