 AFNetworking is a delightful networking library for iOS and Mac OS X. It's built on top of [NSURLConnection](http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSURLConnection_Class/Reference/Reference.html), [NSOperation](http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/NSOperation_class/Reference/Reference.html), and other familiar Foundation technologies. It has a modular architecture with well-designed, feature-rich APIs that are a joy to use. For example, here's how easy it is to get JSON from a URL:
 
 ``` objective-c
-NSURL *url = [NSURL URLWithString:@"https://gowalla.com/users/mattt.json"];
+NSURL *url = [NSURL URLWithString:@"http://api.twitter.com/1/statuses/public_timeline.json"];
 NSURLRequest *request = [NSURLRequest requestWithURL:url];
 AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
-    NSLog(@"Name: %@ %@", [JSON valueForKeyPath:@"first_name"], [JSON valueForKeyPath:@"last_name"]);
+    NSLog(@"Public Timeline: %@", JSON);
 } failure:nil];
 [operation start];
 ```
