I'm really interested to see if the following feature will have positive or negative effects on the culture here -- I feel like it makes everyone slightly less anonymous, which is both intriguing and worrying. I agree, though -- I feel like when you allow users to follow each other, you should probably also include a private setting or a block feature or something. The community here so far seems to be mutually respectful (aka small) enough that it's not currently an issue, but it would be comforting to know that Snapzu is thinking about potential privacy/harassment issues with this feature
