In January 2009, Gnolia lost members' bookmarks in a widely reported data loss incident.

Unlike its main competitor[7] Delicious, Ma.gnolia stored snapshots of bookmarked web pages.

[10] In December 2007, Ma.gnolia collaborated with Engagd[11] to let users build attention profiles from their bookmarks[citation needed].

In March 2008, Ma.gnolia changed its join and sign-in pages to require users to sign up with a verified identity using OpenID.

[19] Ma.gnolia's Recovery Tools allowed users to recover some data from web caches and from other feeds.
