Online PR dos and don'ts
Lindsay Robertson's list of guidelines for how PR people should interact with bloggers is spot on, especially the "pick eight sites" advice:
She picked the eight blogs that covered her client's subject, TV, that she liked the most on a personal level, read them religiously, and only sent them only the content she thought each blog would be into. While the rest of the publicists in her company were sending out mass emails to everyone, hoping to get bites from Perez Hilton, Gawker, HuffPo, or wherever, this publicist focused on a lower traffic tier with the (correct) understanding that these days, content filters up as much as it filters down, and often the smaller sites, with their ability to dig deeper into the internet and be more nimble, act as farm teams for the larger ones. A site can be enormously influential without having crazy eyeballs, because all eyeballs are not equal.
