nope. in fact, when it comes to hand-written blogs, i'd say the opposite. where tgps send TONS of traffic that is rushing to get to the next content, i was surprised to see that the people who stay the longest on our review site are from our blog - and they don't just blast by a few pages, either - they seem to be actually reading the reviews judging by the 2 to 3 minutes they spend on each page.

and there's more and more blogs listed in search engines, which means less traffic, not more.

still, nothing beats the traffic from a hand-written blog
