Reddit — AKA, “The Front Page of the Internet.” Just over 15 years ago, Reddit began as a small and little-known website made by college students, featuring anonymous forums or “subreddits” for topics mostly related to science and programming.

K-Means Clustering on Twitter Politicians

When social media platforms like Facebook and Twitter were first created a decade and a half ago, few could have predicted how influential they would ultimately become in shaping the political landscape of the modern world. [1]

Today, however, just about every politician or public figure recognizes the importance of an online presence. Barack Obama is sometimes known as the first social media President, having leveraged the burgeoning power of Facebook to expand his reach beyond the scope of traditional media, quickly cultivating his image from a relatively anonymous senator to a national icon of hope and change in 2008…

[1] Between YouTube, Facebook, Instagram, Reddit, and Twitter, the uses of social media are many and varied — from uploading videos, posting selfies, and sharing memes to staying in contact with friends and family or making connections with online communities.

However, the social media sphere is also becoming an important…
