Finnish mobile micro-blogging startup Jaiku has been acquired by Google for an undisclosed sum.

Jaiku is a micro-blogging / social networking startup that enables users to post their thoughts, comments and opinions, while other users can keep in touch with friends by viewing their profiles and posting new updates.

It is similar to Twitter, which is seen as the leading player in the space and had also been rumoured as an acquisition target for the web giant.

Jaiku was founded by Jyri Engestrom and Petteri Koponen in February last year. Based in Helsinki, Engestrom previously worked for Nokia as senior product manager for its internet tablet devices.

For Google, this continues a spending spree which has seen it acquire DoubleClick, Postini and others this year.

The move comes soon after Google’s acquisition of another mobile startup, Zingku, and will fuel further speculation about a forthcoming GPhone.

Jaiku’s founders will hope that the deal will work out better than Google’s acquisition of Dodgeball, a location-based mobile alerts service.

The founders bailed out earlier this year, complaining that the search giant ‘wasn’t supporting Dodgeball the way we expected’.
