Where ARE the referrals coming from? And why do people view porn after looking at photos of friends?

There are only a limited number of things typical people regularly do online, I'd be willing to bet the list for a large chunk is something like

1. Email 2. Facebook 3. Porn

In which case you have a 1 in 3 chance that porn follows Facebook.

no, 1 in 2 chance. unless you suppose they can go to facebook after going to facebook.

Well you have the permutations,

(email, Facebook, porn)

(email, porn, Facebook)

(porn, email, Facebook)

(Facebook, email, porn)

(Facebook, porn, email)

(porn, Facebook, email)

That is 3! or 6 total possibilities, 2 of which involved porn immediately following Facebook. which is 1 in 3... ...How do you figure 1 in 2?

On the other hand, you've disregarded the possibility of continuing to browse after doing three things (or stopping prior to three things). If browsing is an endless stream, then facebook has to be followed by one of the other two, which is the angle he was working from. Depends how you frame the question and what assumptions you make; it's ill-defined right now.

Edit: On another note, in his place I would have sanitized my own history; a screenshot showing redtube and tube8 in the "visited" style is tacky, to say the least.

I'm sure there's an innocent explanation! Maybe he was performing some "hands-on" research? :-P

Hidden mid-post: Note: for those wondering how these were chosen, I used related links on Alexa to find some big sites

Suuuure :)

Sexy friends maybe?

Then why leave?
