But, is it morally wrong if Google reward it? Take my friend Merrell Webster for example. He's create a fairly relevant profile page about himself, dropped a link to his homepage, then got bored, let the site and moved on to something else.
That's a perfectly natural thing to do online right?
Also, what kind of a geek driven world would we live in where only those who are serious about online interaction could influence the google rankings with their 'votes' ?
However, it does leave the algorithm wide open for abuse -just like our own Real Life (RL) voting systems.
As always, only Google has the answer...
