Wopular is a news aggregation site that displays the top five headlines from the top fifty newspapers. Each newspaper is displayed on top of another in a three-column format, resembling an online version of a newspaper rack. It covers ten main news subjects - World, U.S., Politics, Business, Movies, Books, Entertainment, Sports, Living, and Travel. It was a simple site built with just four Drupal modules - Aggregation, Views, Panels, and CCK. You can read more about how that was done here.
Since then, there have been several new features; the most significant being the new search bar, which is a search engine aggregator. It's located at center of the header, between the logo and the tagline. I wanted to expand beyond just 10 categories and cover every subject under the sun. However, since this is a one man operation, I didn't want to spend my days looking for a bunch of feeds for every single subject. That would make my days repetitive and quite boring. My solution was to find sites that generate rss feeds for their search results, put them all in a page, and organize them by tabs. The sites I'm using for this feature are top news sites (CNN, NY Times, LA Times), aggregation sites (Google News, Yahoo News, Digg), blog search sites (Twitter, Technorati, Google Blog Search), videos sites (YouTube, Hulu), photo sites (Google Images, Flickr, Yahoo News Images), and search engines (Yahoo, Bing). Oh yeah, I even include Wikipedia snippets. Overall, this search engine aggregates search results from over a hundred websites, mostly news related ones because that's the focus. As an example, here's a search for Barack Obama.
DDEV is the official local development tool of Drupal. And like Drupal, DDEV depends on the support of the open source community.
The Drupal community is alive with meetups, user groups, and camps. However, there isn't a published formula on using Drupal to accomplish the needs of a large meetup, camp, or convention.
