its a little bit like bookmarks. google are trying to mate their search engine with something like del.icious -- all it does is remember where you and your mates have been (ie bookmarked) and shows you that.
my problem with it is that you and your mates kind of get locked into a circle of links that might not be the best.
if i search for "widgets" and there's a hundred pages, i might only visit the first few.
presumably, those first few will then get a boost above the others, because i showed a 'preference' for them. they will then get boosted in my friends SERPs as well, and we all end up with these 3 links sitting at the top forever.
but who's to say they are the best?
just because i popped into the chip shop down the road a few times, it doesnt mean i want to eat there forever.
what happens when new pages are created? the rest of the population may have discovered those and loved them, but me and my mates are still locked into our personal SERPs, where these amazing new sites are buried below our "bookmarks".
