The answer could not be more obvious. Of course they have. The question is, will it destroy what Newsvine used to be and therefore turn it into just another news blog where the opinions of those who participate are not only ignored, but actually laughed at in their irrelevance? Will it be just another site where professional reporters drown out opinions of real people? Yes, it will. Sadly, the corporation attitude will destroy what attracted them in the first place. They can not help themselves.
If you think about it, it's really rather sad. MSNBC took over a vital and raw blog and (via it's corporate stupidity) is in the process of destroying it.
Talk to me (if they allow me to stay that is).
