Of course, Jaiku's been in such a moribund state since Google bought it that it's arguably not as earth-shattering - we now have  a world where Twitter is king of the microblog and Google's own Maps/Latitude is arguably king of location sharing. But location-aware blogging tool Jaiku still has a place in many people's hearts and news is just in that not only is Jaiku now Open Source and running on its final destination server (Google App Engine) but a new S60 native (and presumably also Open Source) client is also coming very soon. Can't wait.
