Boring to read. The key characters are too artificial, the whole thing looks amateur, a bit exhibitionist, lacking dynamics and detached from reality. It feels like the author's characters are incubated from something between James Bond and Transformers types of movies.
I couldn't go beyond the beginning, felt like wasting my time.
My understanding is that the author fantasizes about social networks to become too pervasive in near future. It may be late for the subject, or it could be differently projected to make the story more engaging.
As I can see social networking in general has lost its buzziness and user engagement on the existing large social networks doesn't seem to grow as much as it used to, and the topic has already lost some of its trendiness.
