Twitter trends let users know which topics and hashtags are the most popular at any given time. Although they can often be manipulated to boost the popularity of a Twitter-heavy contingent (looking at you, Justin Bieber fans), trends usually give a pretty good gauge of what people are talking about - you know, what's important.
Trends can be broken down by country and even city. So instead of looking at the trends worldwide, I can look at the trends in Chicago only. This helps users target the conversation and gives the service a more local feel.
And now, Twitter has announced that their Trends are available in a number of new countries and cities.
In all, Twitter has added trend support for over 160 different locations. Some of these are entire countries which have never had Twitter trends before, like Belgium, Greece, Kenya, Norway, Poland, Portugal, and Ukraine. The rest (around 130 locations) are cities getting support for the first time (inside countries that already have Twitter trends).
"Trends are an easy way to find out what people are talking about right now –– around the world, in your country, or in your city. By checking out Trends, you can easily find breaking news and current hot topics that are most relevant to you. To find these new locations, click “Change” in the Trends sidebar on twitter.com, and select the city or country you’re most interested in," says Twitter.
If you don't yet have trends in your city of country, don't worry. Twitter says they are constantly looking to expand trends to more locations. Just last December, Twitter added trend support for 100 new cities.
