I certainly agree with that. The way to displace Google is to work on something they despise as inconsequential, the way the "portals" in the late 90s did search.
There are lots of things they despise as inconsequential: stupid consumerish stuff like celebrity gossip, cool design, things that aren't technically demanding, etc...
Sounds like you're suggesting tackling verticals that Google is ignoring.
The celebrity gossip industry is huge as anyone living in LA or who has bought a Star/People/Enquirer can attest. I think that might fall under the category of news, however.
I think that there might be a strength in ranking sites that have great design as opposed to crappy design. All things being equal, I'd rather read an article on a well designed page rather than on a page whose design is non-existent.
