Viral Marketing: Sherlock Holmes

I love campaigns like this! They're interactive and give the hardcore fans something to participate in and look forward to. They aren't the most effective of campaigns, usually just making the hardcore fans happy and then going unnoticed by the rest of the population, but sometimes they can catch like wildfire.

I signed up for this, and hopefully you will too. We can go on this Sherlock Holmes information chase together.
