What is an online community? An online community is a group of people with common interests communicating and sharing ideas over a specific online platform. I think Tumblr is a platform for online communities. Tumblr was founded by David Karp in 2007, and in 2013 was bought by Yahoo! The site provides not only a blogging platform but also a variety of online communities.
Tumblr is usually used to create personal blogs, be it only posting pictures, writing fan fiction, discussing things that are important to us or using it to display your art. Tumblr is a great platform for that, but not only. There are so many Tumblr communities. People with common interests can find each others blogs, share ideas over private messages or asking questions, they can repost each others posts.
Tumblr has an option ‘Recommended to you’ which makes finding other people with similar interests that much easier. I believe people benefit from tumblr communities in a way that they can find people they have something in common with and start a conversation, so many people have found friends via Tumblr. People tend to support each other in this online community. That is why I personally think it is a good example of an online community.
