In case you don’t know what Jaiku is, its the micro-blogging platform that Google was trying to develop. Powered by Python and probably with the intention to compete with the likes of Twitter, Google seems to be throwing the towel in for the micro-blogging platform.
Or is it? Google says that the best way to run Jaiku is on their proprietry AppEngine platform, but it seems that Jaiku can run independently.
However, the change in business model for Jaiku from an operated-portal to a socially-shared platform suggest that Google has de-prioritized the micro-blogging as a direct product.
