The internet was once a vibrant and diverse landscape of communities, where people from different backgrounds and with different interests could come together to share ideas and learn from each other. However, in recent years, this landscape has changed dramatically. Communities have become increasingly polarized and sensitive, with technical merit, creativity, and genuine discussion taking a backseat to ideological purity tests.

One notable example of this phenomenon is the Alpine Linux situation, where a package maintainer's political views allegedly influenced the rejection of a contribution from XLibre. While this incident may seem isolated, it is symptomatic of a broader trend in tech communities, where good code contributions are sometimes rejected over the author's unrelated opinions.

Another example is the proliferation of ideological gatekeeping in online communities. In some cases, users are banned from IRC channels or forums for expressing preferences that have nothing to do with the channel topic. This kind of behavior not only stifles creativity and innovation but also creates a hostile environment for newcomers and outsiders.

Imagine getting banned from a cooking forum for saying you prefer salt over pepper. Sounds ridiculous? But I've seen the digital equivalent happen repeatedly. Communities that should unite around shared interests instead fracture over tangential beliefs.

The echo chamber effect is another consequence of polarization in online communities. When communities become ideologically homogeneous, they tend to stagnate, as there are no diverse perspectives to challenge assumptions and drive innovation. Additionally, homogeneous groups often develop insider language, unspoken rules, and hair-trigger reactions to anything that feels "foreign," making it difficult for outsiders to participate and contribute.

The gatekeeping paradox is a related issue, where communities struggle to balance the need for quality control with the risk of ideological gatekeeping. While some gatekeeping is necessary to maintain community norms and quality, it can easily tip into ideological gatekeeping, where users are excluded or banned for holding the "wrong" opinions.

The cost of polarization in online communities is high. When communities prioritize ideological alignment over contribution quality, talented people get excluded, innovation slows, and communities become brittle and unable to adapt or grow. The internet as a whole becomes less interesting, less creative, and less human.

So what can be done to rebuild internet communities and restore their former vibrancy and diversity? One possible solution is to create spaces that value diversity of thought and opinion, and that encourage constructive debate and discussion. This requires a willingness to engage with opposing views, to create an environment where people feel safe sharing their thoughts and ideas, and to prioritize technical merit and creativity over ideological purity.

By recognizing the dangers of polarization and echo chambers, and by working to create more inclusive and diverse online communities, we can help to restore the internet to its former glory as a vibrant and dynamic platform for creativity, innovation, and human connection.
