I think the biggest problem with it is the ‘b’. If Nokia had called it LifeLOG rather than Lifeblog, then the intent of the application would be much more clear. As it stands, the idea that blogging is involved (and to most that means publicly blogging) will make some people avoid the application. The truth is far from that, although you do have the option of blogging from Lifeblog, it’s not compulsory, nor required.
