Google says the World Wide Web is a big place and what we all need from time to time is an experienced tour guide.

In making the announcement, Google said it has plans to incorporate other signals, including users connections on Twitter and Facebook, to make sure your recommendations — and those you receive — remain relevant. But here’s the catch — and as far as I’m concerned, it’s a pretty massive one, which ultimately may spell doom for…
