This is an unusual book. It's told from the first-person perspective of the protagonist (Haiku) - alternating between his current experiences and his past articles / rants about his issues with society. It's crammed full of SF elements - Earth is a member of a galactic commonwealth of intelligent species, and humans have "promoted" ("uplifted") various animal species. There are teleporters and replicators. Apartments can produce different "rooms" via holography / force fields and have "storage rooms" in parallel universes. There's a modified version of Asimov's Laws of Robotics. Nanobots. Etc.
Society is dystopian in that people are manipulated and don't have a real say in decisions, but it's not a dystopia in that even unemployed people below the status of "citizens" have a lot of tech and recreation. (Some of this is to meet the requirements of the galactic community.) It's a dystopia in that it's illegal to distribute dissident ideas, but Haiku has been doing that for years (he has attempted to hide his identity, but the authorities have known who he was for practically all those years). It's a dystopia in that there's widespread pollution - and rather than eliminating the pollution, humans have been genetically modified so they aren't significantly harmed by the pollution they would normally encounter. Rising sea levels have covered significant parts of the Earth and the rest has been paved over for the world-wide city for the world's 100 billion humans (as well as other intelligences).
The story centers on Haiku, an isolated malcontent in the year 2150. He's been unemployed for a number of years, which means he doesn't have the status of a citizen. His apartment is relatively small, but even an unemployed non-citizen has access to impressive tech. Since losing his job as a reporter years ago, he's been posting these rants against the government, a messed-up society, dumb people, etc. This is technically illegal, as the government is trying to ensure that the population is docile, inane people content with the status quo. Therefore, he has been posting his rants under a pseudonym, varying which sites he places the files.
He is distressed when the head of a major media source (the Urban Chronicle) contacts him, makes clear he know about Haiku's secret pastime, and insists he become an employee posting the rants only through the Chronicle. That night, his boss is murdered and he becomes a leading suspect. Haiku decides he better investigate the murder himself in order to avoid taking the rap. To get to this point, it's taken about 150 pages. Although those pages didn't drag, some readers will feel that's rather long for a mystery to get to the commission of the crime.
I don't have a better word for his articles / monologues about society than "rant". On the one hand, he sounds atypical, angry, and disdainful of the average person and government. But he doesn't sound delusional or unbalanced in his commentaries on society. That is, in the context of a dystopian setting - otherwise he'd be paranoid. On the other hand, he does have a thing for having a vast array of weapons and a habit of using them to humiliate or incapacitate those he has strong disagreements with or feels threatened by. He certainly doesn't come across as a calm, respectful, law-abiding, socialable hero. He's living on the edge. But, somehow and relatively speaking, he's the good guy.
Haiku's adventures include dealings with a government agent with a grudge against him, his apartment AI who has itself installed into a robotic body, one of Earth's wealthiest men / government leaders who seems to want to let Haiku publish his rants, a virtual reality world, the electronic consciousness of his mother who is employed by organized crime, some uplifted animals - including a security guard who was fired after the murder, a very non-human alien whose species has a special interest in humans, a dim-witted neighbor that Haiku has been playing practical jokes on for years - who gets very angry when he gets smart enough to realize it, the new boss at the Chronicle who has a dirty little secret, etc.
The rants between the story sections sometimes give background useful for the upcoming story section. They always give atmosphere and extra detail to this future society.
This book probably isn't for everyone, but I found it to be a good read with food for thought. That's worth noting as it's from an unknown writer.
