network allows you to share with your followers
of 140-character messages. It has more than
200 million users worldwide. Initially, it was not so
accepted, since it was seen as a status update;

competition, in fact constantly updates comparisons

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.
