Twitter is one of the best platforms for creating and growing your personal/professional learning network (PLN). The strength of this microblogging tool lies in its easy accessibility and its sweeping widespread among a larger and diversified base of users. Creating a PLN in Twitter starts with following Tweetors whose tweets can potentially be of an added value to you. A rule of thumb here is that before you follow anyone, make sure you peruse through the tweets they have been sharing and see if they intersect with your own interests and goals. If so, use the snowballing strategy to find other similar Tweetors to follow. In other words, when you find somebody worthy of following, check their following list, chances are he/she is following other like-minded people you might want to add to your PLN as well.
