15. YAHOO
However another service that came out of nowhere and a great bet
of hundreds of millions of dollars that made Yahoo this project
managed to consolidate itself as one of the web sites of 'discovery'
if I may say so there is always that we do a query on any search
engine one of the top results Wikipedia has them; This versus
between yahoo answers and Wikipedia already talked about
before.
Yahoo Answers is a service that allows you to make any type of
questions, according to its category and any other user can answer
this question and others may also qualify and choose the best
answer.
It is undoubtedly the alternative to more casual Wikipedia that exist
today in the market of web services and social networks.
