You're right, the pie is always growing, but there are some queries that just work better on Twitter, even though you might get reasonable results on Google with enough digging. In those cases, Google loses as people learn to start trying Twitter first. An example: Last night I was trying to find a stream of a live hockey game. Google was finding lots of forum threads about previous games, but nothing current. So I tried Twitter, and there was a link in the second result. Next time I'm looking for a live stream, I'll probably search Twitter first.
