Unfortunately it seems that none of you understood my question so I'll explain it a bit more clearly. I understand pagerank and hubscore are separate things. I wasn't talking about linking my hubs to my profile manually, or the other way round, as there is already a link there, I was just talking about my profile pagerank influencing the hubs.
My hubscore profile page contains links to my hubs. If I drop backlinks to my profile page on external websites, which boost the pagerank of my profile, will that trickle down to the hubs that are linked from my profile, boosting them as well?
Lets say that I get my hubpages profile page up to a pagerank 3 for example, would that then count as a pr3 link to each hub, or is it totally irrelevant as the link between profile and hub does not seem to be recognised as even existing by most link checkers, or at least the ones I've found?
I know google crawls the profile pages, but if the links from the profile page to your individual hubs are either not visible to google or are nofollow links, then profile pagerank is utterly irrelevant.
As hubpages is called hubpages, the thing that makes sense to me is that your profile page is your central hub, with all your articles linked from that, so it would make sense that if your profile page is boosted, that would have an effect on each article. But maybe hubpages doesn't work like that.
I hope this is clearer this time.
