Jaiku tells Google all your secrets.

Good read here analyzing Google's recent acquisition of microblogging goodness Jaiku and how it may play into Android and Google's mobile strategy.

The author focuses on the location awareness built into Jaiku. Originally this functionality made use of cell tower triangulation APIs on the Nokia S60 - although obviously GPS would be easier and more direct - and would also serve up the phone's status (In a Meeting, etc.).

As this blogger, Jonathan Mulholland, puts it so well:

If you’re a user of Jaiku, or Twitter for that matter, look back through some of your posts and you’ll see that you’ve built an outline profile of your life. Reading through my Twitter and Jaiku pages it’s reasonable easy to deduce that I’m a Mac geek, a fan of American TV dramas, enjoy listening to Radiohead, suffer from occasional migraines, like Indian food etc etc. Now consider what value is added by a service that knows where you are and also whether it’s appropriate to contact you (through your mobile phone) as you post updates.

Kinda scary, honestly.
