Interactive news like huffington post is now so common. Trapro is the another approach to interactive media. It compiles the issue focused news from each individual or issue related group. Journalist can not cover every single issue around us. Nowadays our interest is so diverse that it is difficult to meet our interest by a newspaper, TV report. This is supplemental to those niche in our interests. There are so many interesting inssues that I often neglect such as the issue about STEP on the street which may cause trouble for wheel chair riders. The group trys people to upload the photo of STEP existing around you. It is easy to start and interact horizontally.
