Probably the best current use of this card is to turn that -1 News Team into a 2 point agenda. If you're playing this along with Temple of the Liberated Mind, All-nighter or Hyperdriver or Amped Up then you'll only be too happy to take News Team as an agenda.
Another use is for Fan Site although this has significant downsides when compared to News Team. For a start, Fan Site has to be out before the corp scores an agenda. Second, the corp now has an agenda which they might be willing to forfeit in order to stop you cashing in Liberated Chela.
Notoriety has fewer problems than Fan Site - the corp doesn't need to score first although you might not like the economy of turning 1 point into 2 for the cost of getting Liberated Chela set up - however if you're on six points it could win the game for you.
