I was wondering should there or will there be a tag for the 2014 World Cup? I know there was an effort to promote the site before using the Sochi 2014 Olympics so should the same be done with the World Cup? I don't know whether the previous attempt to promote the site resulted in more new users or not but if it did then the World Cup would be another good opportunity to promote the site.
It's a good way to raise interest to the site, but after the event is over (examples: london-2012 sochi-2014), the tags are hardly ever used again (not to mention only 9 questions among the two example tags). Most of the questions are usually general Olympic questions.
I am not against promoting the site for the World Cup as we did for the Olympics. However, I'm not so sure tag creation is necessary for the World Cup given previous results for the Olympics and already having tags in place.
