Agile development has a lot of advantages, the biggest being the ability to respond to a change in 'requirements'. I put requirements in quotes because agile development doesn't really have some 100 page specification sitting around -- the requirements can change as the product is developed and people give feedback.

One of the things that has changed for FanConcert is how it handles lists of objects, like a list of upcoming concerts at Capital Music Hall in Ottawa.

This used to be a custom list that looked something like:

http://www.fanconcert.com/concert/venue_upcoming/2

Now it's a concert search instead. Users can see the search form with the parameters filled in and then change them if they want to. Searching gives every list a common look and usability.

The URL has all of the search parameters in it, so it can be easily manipulated. Not only on the URL bar in the browser but also by third party tools that hook into web searching, like Roy's FireFox Search Box extension -- I'll get him to update it. ;) Sure, the URL isn't as readable as it could be but I think it's more useful. The URLs wouldn't have been very readable for non-English speakers anyway.

When I get all of the lists converted to searches, I'd also like to allow users to save their custom searches so they can easily go back to them. A list of saved searches will be on the user's summary page, which appears after the user logs in.
