Rockstar is giving GTA Online players an incentive to log on today and tomorrow as they'll earn twice as much GTA$ and RP as normal. With the potential to own a second property and more content updates planned, that might just be something you want to take advantage of.
At this point, I'd be afraid to return to Online out of fear that I would be utterly outclassed and outgunned by everyone else. It's the same fear I have for most of the multiplayer titles sitting on my shelf. Sure, there's passive mode, but that defeats the purpose, to some extent.
