To be completely honest with you, I kinda hit my viral campaign limit with The Dark Knight's amazing marketing blitz and haven't really rebounded since. Maybe it's because there hasn't been a campaign quite as genius as the one for that film or maybe it's just not that interesting to me anymore -- either way, I'd rather leave the extreme viral hunting (and reporting) to other sites and just mention the little bits of coolness I happen to come across while surfing the web.
Like these new viral ads for Transformers: Revenge of the Fallen, which look to be a part of something larger and more complex, but I'll just settle for the "Hmm, that's kinda cool" factor.
