UN, UNICEF and WHO tweet almost two to four times a week. Tweets are usually in accordance with the organizations' objectives. The UN discusses issues related to various international issues and the provision of aid to countries in need, such as the UN-approved access to aid in Syria, as cited in a UN tweet “Passed unanimously, the Council resolution Security Agency requests access to aid in Syria. Information here: j.mp/1jXA8AO.” WHO shares health-related facts and reports, such as “.@georgyishere Seasonal #flu is circulating around the world. Read more on our factsheet goo.gl/SLZQUi.” UNICEF shares the status of children and related issues such as "Providing safe water to children and families affected by #Haiyan pic.twitter.com/qU7glahSCi @unicefphils". The tweets of these organizations (UN, UNICEF and WHO) refer to our course, i.e., global economic issues. The United Nations tweets concern international peace and security, the promotion of human rights, the promotion of social and economic development, the protection of the environment and the provision of humanitarian aid in times of famine, natural disaster and armed conflict. UNICEF tweets address the rights and well-being of children in 190 countries and territories, focusing on reaching those most in need. WHO, the United Nations health agency, tweets about health status, health problems and new cases of diseases detected around the world. These organizations tweet about recent global economic issues such as international cooperation, latest events, promoting children's interests around the world, and global health issues. You can attract more Twitter followers in many ways. It can be achieved by creating an effective profile, tweeting during peak hours, developing a niche, posting thought-provoking tweets, and responding when people retweet. In my opinion, the United Nations International Children's Emergency Fund (UNICEF) is the most effective user. UNICEF promotes the rights and well-being of every child in 190 countries and territories, focusing on reaching those most in need. He has a huge following. He tweets regularly about issues related to children around the world, their status in emergency situations, what they are going through and what is being done to help and support them. UNICEF also says it is putting a spotlight on innovation for children. The World Health Organization (WHO), the United Nations health agency, tweets about health status, health problems and new cases of disease detected. Nowhere is it mentioned what measures have been taken by WHO to curb and cure such health problems. This is why I believe WHO is the least effective user. I would highly recommend it
