Plurk

Plurk (/ˈplɜːrk/ ^ⓘ) is a free social networking and microblogging service that allows users to send updates (otherwise known as plurks) through short messages or links, which can be up to 360 text characters in length (as of 2016).

Updates are then shown on the user's home page using a timeline, which lists all the updates received in chronological order, and delivered to other users who have chosen to receive them. A unique feature of its timeline is horizontal scrolling which is unlike any other popular social networking or microblogging websites like Twitter or Facebook, where users can see more posts running horizontally across the screen, with previous plurks to the right. Each of the threads shows timestamps below the timeline frame, and a counter for the number of responses; a thread can have as many as 300 to a thousand responses. Users can respond to other users' updates from their timeline through the Plurk.com website, official mobile apps, by private or instant messaging, or by text messaging via compatible third party applications. Also unique to the site is the ability to post anonymous plurks using the "whisper" qualifier, affording users the ability to hide their username or identity.
