Firstly, Minecraft just passed 10 million registered users!
Now, I've received a few emails about Bill S.978, a new bill proposed in the USA, which would make it illegal under certain circumstances to share videos of copyrighted materials over the internet. The problem is that it appears to also make it illegal to upload videos of games, such as let's plays and speed runs. And I love watching let's plays and speed runs.
Here's a great video on the subject I found via Reddit: Youtube.com
If the bill passes, I suspect many game companies (including us) will add a special clause to the TOS specifically to allow posting videos of their games. A huge part of why Minecraft has grown so fast is the YouTube community.
