The figure below shows the View Window. It resembles an aggregator with lots of information shown. Again, colors play an important role. Entries in blue are incoming entries, i.e. entries that have been received. Entries in red are outgoing entries, i.e. entries that have been sent. And entries in purple are entries that have been shared. The star with a smiley icon shows whether the user has liked an entry and decided to share it. If, within a group of subscribers, many people have shared a specific entry, then the three stars to the right will be shining. And if someone has added a comment to the entry, the far left star will be shining. Thus, if all five stars are shining, then this is a very relevant entry within this social network.
The icons in the top bar are guides to help the user filter entries. If the user wants to filter Science and Technology entries, for example, he or she can select the tag icon, which displays the user’s own tag cloud, from which he or she can select the Science and Technology tags. In the search box it will appear the following string: "tags(Science and Technology)". Other combinations can be done as well.
It is important to remember that even though the entries have been tagged as Environment by Debbie, they are tagged as Science for Nick. But these entries are not published in Nick’s Science node unless they have been shared by Nick himself.
