Official Google Blog: Google learns to crawl Flash

Now that we've launched our Flash indexing algorithm, web designers
can expect improved visibility of their published Flash content, and
you can expect to see better search results and snippets.

Wow, this is big! There goes one of my main arguments against primarily Flash driven sites. I expect as the ability to properly index alternative types of media, that is items other than text and images such as Flash, video, and SilverLight, it will slowly and fundamentally change the way websites are developed, or even thought of for that matter. Why bother a traditional, hierarchical website when you can just invite chaos and allow your users to explore through a semantic search? Think Gmail vs. Hotmail.
