It could be said that Tumblr is a website where online communities can be found. At least, it was what I first thought of when I was thinking about online communities.
Tumblr is a blogging platform as well as a social networking site. It was founded by David Karp in February 2007 and was acquired by Yahoo! in 2013 for around $1 billion.
The main reason that I think of Tumblr as being a website of online communities is because of the way the website is used by ‘fandoms’. Fandoms are groups of fans of almost anything, from TV shows to movie franchises, to books and musicians. Hundreds of fandoms use Tumblr in a way that is almost like an online community.
As it is a social networking site, this isn’t abnormal. Like Twitter, you can message people who may have a similar interest or blog type and users find a common interest with the thousands of other users who blog about the same thing.
The style of blogposts are also in a conversational style, and the way you can build your own blog shows that there is a more personal side to the website, where users can interact with each other.
