In general, social media platforms are perceived as the most popular representation of the social use of the Internet. Forums, online communities, social networking sites, chatrooms and many others are social spaces where users present themselves, share multimedia content with other users and create social interactions. For many, communicating on social media platforms is a daily habit, a place for work and a source of entertainment to the extent that most of their social life is experienced online. On the Internet, people can find various ways and platforms to socialise and connect with people with same interests.
In this, photography seems to be a widespread hobby. Platforms like Flickr, Pinterest and Instagram are an example of this tendency. Considering Instagram in particular, it can be observed that the platform provides various opportunities (online photo contests and offline InstaMeets and InstaWalks discussed later) to socially interact with other users and create relationships of interests, that is the passion for photography. This might be one of the reason why many users consider Instagram as belonging to the family of social networking sites. Giulio, for example, due to his love for photography, considers Instagram a real social networking platform, rather than a pure photo gallery. He believes that the presence of photographs is precisely the reason that encourages people to engage with each other. This type of social interaction is based on the common interest in photography.
Structurally, Instagram does not offer a list of friends as other social networking sites. Instead, it offers a different type of connection among users, the ‘following’ button. In fact, the type of connection offered is the possibility to follow other people’s Instagram account, which allows users to like and comment on photographs. These types of interactions (following, liking and commenting) are publicly visible to all users by default, but they can be changed making the appropriate modifications to the privacy setting. This can give the opportunity to create private accounts where photos are visible only to the people approved by the account owner. In addition to considering Instagram as a social networking site, it is also a platform of communities of interest, where photography is easily recognised as eliciting social interactions. Broadly, communities of interest are groups of people who share common interests. They exchange ideas and support about the given passion. In fact, they do not only carry out transactions with one another, but their interactions are generally focused on specific topic areas.
