Full of good advice but not specific to "the digital age"

Book full of advice and in that sense I recommend it. But I bought it hoping to find specific advice to new media such as twitter, Facebook & co and even if they are cited, it's more anecdotal than anything else (in every sense) and which, in my view, not enough to justify the "In the digital age" of the title. Hence the 3 stars only.
But, otherwise, as I write above, I recommend the book :-)
