- Technology which can extract frightening amounts of information from search history, location data, and other data sources. It's not 2012 anymore when a google or FB ui just showing the places you had been was enough to get me to give over that kind of data.
- Ad based search engines literally filling the search page with ads.
- SEO spam so severe that the non-ads are generally terrible pages anyway.
Given all of this, and a young daughter who will be browsing the internet in another year or two - I'd be willing to pay for a search engine.
