It seems odd that people make friends through a social media platform, but it happens. People connect via a common interest, interact and form friendships. When this happens between many of the same people it forms a on online community. The interests which bring people together can be sports; ‘Football Twitter’ is a thing. Or it could be a political affiliation which brings people together; people who share a passion for a particular cause connect over the internet and it creates a platform for discussion.
These communities are largely positive. They bring people together, allow people to find other individuals who share their perhaps niche interests and are a great way for the introverted to express themselves in a comfortable environment. There are always negative aspects to social media: the possibility of receiving abuse, etc. But thankfully we all have the option to mute and/or block people with whom we don’t wish to interact.
Participants in online communities like this can benefit from engaging in debate and listening to (or reading) other people’s points of view on topics in which they’re both interested. One can educate themselves and share ideas on a platform where they will receive mostly honest feedback and discussion.
