So what if, hypothetically speaking, Google decided to release its code, make it open source, and let millions of seos, marketers, hackers, webmasters, soccer moms, ex-presidents, and NBA super stars do with it as they please? Would the world be a better place, would it be possible to even consider? I don't know, but the things all these people could create would be interesting. I am guessing though open source will have to start small and work its way up to the bigger players. For Google, open source is a bad idea, for other niches and directories its a great idea.
Found a neat little post over at SEOchat, about open source search engines and the possibility they would hit mainstream.
