Google's Competitive Advantages

Recently I was over at Topix.net and glanced at their blog and found a great post about Google by their founder Rich Skrenta which highlights Google's competitive advantages.

...the story is about seemingly incremental features that are actually massively expensive for others to match, and the platform that Google is building which makes it cheaper and easier for them to develop and run web-scale applications than anyone else...While competitors are targeting the individual applications Google has deployed, Google is building a massive, general purpose computing platform for web-scale programming.

I also just finished reading Emergence by Steven Berlin Johnson where he reviews some emergent software and social networks such as Slashdot.

While at Slashdot I noticed they too were eating up Rich's post, as the blog community at large is (last I checked MIT's Blogdex it was the most rapidly spreading idea on the web).

After reading Emergence it became more apparent how smart the Topix news idea is. After reading his post it became even more apparent how smart Rich is. I am just wondering how they will be able to take news market share from the big search monsters. Obviously doing news way better works, but even Rich's own post state how amazingling cheap CPU cycles are at Google. How will Topix overcome Google's competitive advantages?
