New Google Feature

I've been sitting on this for a few weeks now -mainly due to my own laziness but I thought I'd finally pad it out a little. It would appear that Google have release a new method of ranking your own results for certain terms:

Once you've promoted a page you'll notice a little green arrow to the right of the title link and the results will come back in this order every time you search on that term while you're logged in.

At the moment I think it's just stored against your profile but I would imagine at some point in the future they'll start monitoring what everyone else is promoting and adjusting their results accordingly.

What I'm interested to know about is how it affects SEO, I can't imagine they'll add too much preference to the promotions otherwise we could be in for another Google Bomb situation where your competitors promote or demote your site.
