When google upgrades their algorithm? Are you talking about the "related keywords" buzz? That might be good for people with actual (decent) content.
Nobody will know the answer to that. That is how we all learn. When the update happens everyone scurries around and within a few days you will see an intelligent post by a respectable person on this forum who will give their two cents. The bottom line is, you'll learn who to listen to and who not to. There are many garbage posters here so be careful.
google has done a lot of crazy things in the past and people ended up losing their main income because of it. But Its probably safe to say that google isn't looking out for themselves, but the internet as a whole right?
A buddy of mine who used to work for Google used to tell me, they try and make it as hard as they can for people to optimize their sites, but of course people still do. I think it will benefit some people, but hurt others, but no doubt rankings will shift around like crazy.
First we need to know what the changes are before you can decide whether it will be good or bad I don't think anybody will be able to tell you this since google has always been tight-lipped when it comes to algo issue.
