Everyone knows what Twitter is today. Has anybody heard of Jaiku? Well, me neither, until today!
Apparently Twitter got competition. My cursory look revealed that Jaiku is more feature reach and options laden than Twitter.
Jaiku is operated by Google, so if you already have GMail getting in contact with your friends is a breeze. Additionally, anyone can operate its engine (JaikuEngine) and it is Open Source (sweet)! Go to http://tinyurl.com/awkpcf for more info.
Just go and explore it or join me on Jaiku http://arthurz.jaiku.com/
Cheers!
