By making Twitter part of Google they've infected Twitter with spam. No wonder they've stuffed it down the bottom of the SERPS, Google don't think Twitter is relevant at all, they are trying to destroy them!
Never thought of it that way before, Well done :)
It gives incentive to spam Twitter, therefore undermining twitter itself, Not sure if that was the initial plan, but it does look to be working.
