What's going to make the difference between the 3 Search giants Google, Yahoo! and MSN?

  • All of them have a search engine with a design more and more similar...
  • All of them have a blog (MSN just opened its blog)
  • All of them have a toolbar
  • All of them try to have the bigger index
  • and so on...

Maybe the users will make their choice, mainly based on relevance.
