* Yahoo Answers
Quora ( 100M users [1] ) and Stack Exchange is now the default question & answer sites.
* Yahoo News and Yahoo Sports
Google news and search ( 44% of Google searchers scan the news results [2] ) already provide these features. I used to use Yahoo Live Scores, but now I use Google.

* Flickr
Google Photos ( 100M users in 5 months [4] )
