Search as a paradigm will continue to be probably even increasingly important because the information that's out there is only going to grow exponentially - and the only way to sort through all that is by some form of search.

What's been important with Flickr is the community that's been there from the beginning and the serious photographers that are there creating and sharing great content. If we lose that at some point then I think we have potential issues, but so far we've been able to do a really good job of maintaining that.
