The OP mentions that the second half of the book chronicles the author's time at FB. This was excerpted in Vanity Fair, and the HN commentary from early this month is here:

The NYT reviewer in the OP was repelled by the author's pose ("The aphorisms are sometimes lazy, the facts can be sloppy, and the studied cool – all the while insisting that “I am the uncoolest person you will ever meet” – can be grating."), but ultimately able to get past it to the anecdotes and "directionally correct" analysis in the book.
You can note that the HN readership also had a similar reaction, with varying degrees of being able to move past the initial impression.
