Per Guillaume's feedback ( http://share.ez.no/community/profile/10039 ), adding a "what's new" entry in the user toolbar at the top-right corner of the page, once logged-in, would help users stay up-to-date with the latest content since their last visit.

The "What's new" link should lead to the already existing http://share.ez.no/content/new page.

Quora does this well (see screenshot).

Thanks Guillaume for this
