That's already the case. My personalised search results pages are often way better than the generic ones. I added the Hacker News circle and a lot of you link a lot of very interesting and valuable articles.
Do G+ circles really influence search? If so, that's super annoying, because then I have to be careful what G+ circles I join. Personalized search is already annoying enough.
You don't 'join' circles. You put people /in/ circles.
They influence search by increasing the relevance of links by people sharing them or +1ing them. You can just turn them off on the results page it seems but I have found it very beneficial.
Why is it already annoying? The only reasons I've heard have been hypothetical.
Putting people 'in' and joining is functionally the same, that's what I meant.
The reason it annoys me is that I usually want my searches to be objective and global, not influenced by my preferences. I suppose a solution might be if their UI showed the influence clearly.
Should have figured that was the case, but even not logged in Google's search results are so much better that they have a practical, if not legal, monopoly on search. Trying to have any privacy these days is like trying to stop the tide with a sand castle.
