While it is possible to read the messages on Twitter about a trending topic, it is not guaranteed that you will see any links in the messages that you are reading.

That’s where the web service ShowMeTrend comes into play. The service links the top 10 Twitter trends of a particular day to Google News articles about that particular topic.

The trending topics get updated regularly, and it appears as if the links from Google News are pulled more or less whenever they appear there. All news articles are linking directly to the site they have been published on. It is furthermore possible to open Google News’ listing of all related news, or to go back and forward one news entry on the ShowMeTrend website.

Selections can be made at the top to switch from the day’s worldwide trends to country specific and date/time specific trends. About ten countries can be selected, from Germany and the United States to the Netherlands, UK or Brazil. The service’s back catalog of Twitter trends begins in October 2011, which is an indicator that it is a relatively new service. Users can not only select the date but also the time of a day to get a listing of trending topics.

One of the issues that the developers need to fix is the lack of links for some topics. Some trends show a white listing and not a single news item. One of the options here would be to either improve the search algorithm or to use additional news sources besides Google News.

ShowMeTrend is an interesting service for researchers, marketing agencies and individual users. Have you tried the service? If so, what is your take on it?

Trendsmap is a Google Maps and Twitter mashup that solves both of these problems. The tool displays a world map that is displaying popular topics based on the region the user is looking at. It is for instance possible to see right now that the people in the Philippines are tweeting about the typhoon Pepeng while the most popular topics on the US west coast are the movie Zombieland, Halloween and the NL West Champs.

Since Trendmaps is a Google Maps mashup it is possible to zoom in and out of the map. This only makes sense in regions of the world where Twitter is a popular form of communication. A click on a popular topic will display trends and latest messages on the same screen. The box that is displayed on the right side of the website usually contains a short description of the trend and links to websites for additional information.

Trendsmap is an interesting Google Maps Twitter mashup. More so for researchers and users who like to stay up to date on certain topics.
