Pipes really does allow you to "aggregate, manipulate, and mashup" the web. This tool is so powerful its hard to even begin scratching the surface. Create aggregated rss feeds for... goods or housing in your area, news from around the web, price alerts from auction sites, and anything else you can think of! If you ever wanted to dabble in programming, but didn't want the code thing to get in the way, here's your chance.

This service is a really impressive, innovative way to enhance your website/blog/etc to add contextual, overlaid "buckets" of media, links, and news wherever you want on your site.

Everystockphoto.com is a license-specific photo search engine. Currently we index and search millions of freely licensed photos, from many sources, and present them in an integrated search.

Google offers a number of tools to help examine search trends over different time periods. In addition to Zeitgeist, which looks at an entire year, Google also offers Google Trends and Hot Trends.

Here's more about Zeitgeist from the site:

Pulling together interesting search trends and patterns requires both computing power and human power too. Search statistics are automatically generated based on the billions of searches conducted on Google. With some help from humans, and a pigeon or two when they have time, these statistics and trends make their way from the depths of Google's hard drives to become the Google Zeitgeist findings. We should note that in compiling these Zeitgeist lists, no individual searcher's information is available or accessible to us. What you see here is a cumulative snapshot of interesting queries people are asking – over time, within country domains, and some on Google.com – that perhaps reveal a bit of the human condition. We appreciate the contribution everyone who searches on Google makes to these fascinating bits of information.
