From VOA Learning English, this is the Tech Report.
Johannesburg is tweeting up a storm. The South African city leads the continent of Africa in Twitter usage. A new study shows that Johannesburg averages one tweet every 13 seconds.
The public relations company - Portland Communications carried out the study called "How Africa Tweets". It gathered information about geo-tagged tweets from October to December of 2013. A geo-tag records position information of a tweet. The study shows that over 600,000 geo-tagged tweets were posted during the three months.
Allan Kamau leads the Nairobi, Kenya office for Portland Communications. He says it is no surprise that Johannesburg leads Africa in Twitter use. South Africa has the highest smartphone usage of any country in Africa.
"Also, Egypt featured highly - Cairo, Alexandria, other top cities in terms of active tweeting. Moving to East Africa, Nairobi is the most active, not surprising. It's sixth most active on the continent," said Kamau.
But Mr Kamau says geo-tagged tweets do not represent the total number of tweets from each city. But he says, they do provide a dependable estimate of Twitter usage.
"It should be a broad indicator of the trends within the Twitter sphere. It's representative enough for it to be a broad indicator of Twitter activity, trends in terms of how people are using it," said Kamau.
The company did its first study in 2012. Mr Kamau says the largest change he has seen is in how Twitter is being used.
"In terms of topics, one of the shifts that we've seen is when we look at our survey in 2012 was that it was very much social conversations online. We're seeing much more corporate. Many more companies having a presence online, so brands having a greater share of voice, being more active, engaging consumers directly," said Kamau.
He says consumers are now using Twitter to discuss faulty products or bad services.
"It's a much more public place, and also it's a direct and public channel to complain. And people organize very well on social media," said Kamau.
Kamau says companies, organizations, and even sports teams - now value Twitter as a great resource for social involvement. The leading topic of Twitter across Africa is football - a sport known in the US as soccer.
"Africans love football, are very passionate about their football teams, and Twitter provides a platform again for fans to get behind their teams.The most mentioned football team was Johannesburg's Orlando Pirates. It's just a fantastic platform for that kind of thing," said Kamau.
Mickey Modisane is the public relations director for the Orlando Pirates. He says the team's Twitter account has 145,000 followers. He says he is excited about his team's Twitter Popularity.
And that's the VOA Learning English Technology Report.

这里是美国之音慢速英语科技报道。
约翰内斯堡迎来了发推特的大潮，这个南非城市在推特使用上居于非洲前列。一项研究表明约翰内斯堡平均每13秒发出一条推特。
波特兰传播公关公司进行了名为“非洲如何用推特”的调查，收集了2013年10月到12月有地理标记的推特信息，地理标记记录发推特的位置信息。研究发现这三个月内发了60万条有地理标记的推特信息。
艾伦·卡马乌是波特兰传播公司驻肯尼亚内罗毕办事处负责人，他说对约翰内斯堡成为南非最大推特使用地并不吃惊，南非的智能手机使用量是非洲国家中最多的。
“另外，埃及的推特使用也很普遍，开罗、亚历山大和其他城市的推特活跃度也很高。在东非，内罗毕是最活跃的，这并不令人吃惊，按活跃度在非洲排名第六。”
但卡马乌说有地理标记的推特并不代表每个城市发的推特总数量，但他说它确实提供了衡量推特使用量的可靠估计。
“这是推特趋势的广泛指标，其代表性使之足以成为衡量推特活跃度--也就是人们如何使用推特--的广泛指标，”
该公司2012年做了第一次调查，卡马乌说他所看到的最大改变是人们如何使用推特。
“在话题方面，一个变化就是，2012年的时候主要是网上社交，现在我们看到更多企业开始在线，这样品牌就能发出更多声音，更活跃，能直接与消费者交流。”
他说消费者也用推特来谈论糟糕的产品或服务。
“这是更像是个公共场合，是个直接和公开的投诉渠道，人们在社交媒体上组织有序。”
卡马乌说公司、组织甚至运动团队现在都将推特视为社交的重要资源，非洲推特上最重要的话题是足球，美国称之为英式足球。
“非洲人喜爱足球，他们很热爱自己的球队，推特为粉丝们提供了一个亲近自己球队的平台。人们谈论最多的足球队是约翰内斯堡的奥兰多海盗队，在这方面推特是个很棒的平台。”
米基·莫迪桑是奥兰多海盗的公关总监，他说该球队的推特账户上有14.5万个粉丝，他说他对本球队的推特任人气感到兴奋。
