Google is opening the source code to its Jaiku microblogging service, according to Ars Technica. Unfortunately, it doesn't appear to be a move ahead for the service -- at least not at this point -- because Google is discontinuing its involvement with the project. Writer Ryan Paul points out that when Google bought Jaiku last year, many thought it would be a competitor for Twitter, but it was not to be.
The move is apparently part of Google's larger effort to cut costs and streamline its services. Jaiku will still operate in Google App Engine, the story says, and the code will be maintained by volunteer developers, as well as the larger open source community.
Maybe the volunteer developers and others will take up the cause and expand Jaiku into a bona fide Twitter competitor.
