If you're following more than 100 people on Twitter, you probably already find it very difficult to follow back users who started to follow at first. This could change with the new roster system that the microblogging service began testing among some lucky users, as the company said on the blog.
The lists will organize people you are following in groups of, say, friends, colleagues, celebrities, bloggers, etc. By default, each user lists are public, although users can opt for private. The grace of this is that others can begin to follow the lists that others have done and that interest them. "We started working on these features by the frequent requests we receive from people who are interested in a better way to organize information on Twitter," said Nick Kallen, who is in charge of the project. Kallen said he is also working with application developers so that they also bear the lists.
