Senator Hart responded to three reader comments over on his blog.  There's been some doubt expressed in the blogosphere over how "real" this endeavor is - suggesting that the blog will be used as just another medium for polished campaign tidbits and not the give and take the blogosphere expects.  I think this is a good demonstration that Gary Hart is willing to use this medium to not only get his message out but more importantly hear what people think.  This bit in particular gets me excited about the possibilities:

I welcome a dialogue with Chuck and others on this, since it needs to be further thought through. I understand the complexity of the proposal and can think of a number of questions myself, but let me know a better alternative.
