If somebody were to launch a search engine to compete with Google, what weaknesses of Google's do you think could be exploited?

I think there are a few.

First, Google is extremely porn friendly. It sort of already has a "porn search engine" image going on, and that could be emphasized to the "family friendly" market.

The other huge weakness is Google's blind willingness and eagerness to include as many pages in the index as possible. Only 2% of indexed pages need to be indexed, IMO. The other 98% are MFA crap.
