I hear this "polluting the stream" argument a lot .. but what is really so bad about someone cross-posting from Twitter ?

Wouldn't that be a great way for Google to capture some of the Twitter content (which would be more valuable IMHO) ?

I update tumblr, which posts a to my facebook and twitter. The twitter update posts itself to G+, and facebook again. ~70% of my friends see that post at least two times, if not four.

It sucks.
