Jaiku is a micro-blogging service owned by Google since 2007. Jaiku is almost as simple and identical to Twitter. If at all, it’s a slightly prettier looking interface than Twitter’s. The features are also almost identical. There are channels for users to access and have a discussion. Replies to posts made by others are done in the same page itself rather than posting through your profile page in a forum-styled text area.
Jaiku has badges that can be embedded into personal web pages or sites. Customising the profile page is also available for all users. A background colour can be selected and also the background image. Similar to Ping.fm, updates can be sent to the service through chat bots.
