Youre smiley app doesnt even work. Goes into a browser refresh loop (using latest Firefox)

Thanks, we're aware that it's been broken and are in the process of updating it. It should be ready in the next couple of weeks. Sorry for the inconvenience. Pete -- 563683308 11:52, 14 October 2009 (PDT)

Ok, this is extremely frustrating, Facebook. You guys keep telling us that you want our opinion and to keep sending and posting our feedback. However, whenever your community of developers posts specific, constructive feedback, you completely ignore it. From my POV the changes that you're making to the platform are well-intended, and in most cases, positive. Unfortunately though, because of the haphazard and sloppy way that you guys are rolling out the changes (and the poor manner in which you're communicating those changes) you are turning off your entire developer community. FACEBOOK, PLEASE GET YOUR ACT TOGETHER!

Ok, here's my $.02:

What would be REALLY helpful is if the Facebook team could put together a series of step-by-step tutorials for each area of functionality on the new platform. Each tutorial should include:

1. A task-centric title for the specific functionality (such as "Adding content to a user's Info tab"). Think about these tutorials and titles in terms of "Here's how to do X" where "X" is one of the ways an application can interact with Facebook.
2. Screenshots of the targeted area of the site (such as those on the "Anatomy of a Facebook Application" page). Ideally you should include 'before' and 'after' screenshots to illustrate the relevant changes.
3. Concise and specific code examples for each of the major client libraries (PHP, Ruby, Java, etc.) Each code example should be less than 100 lines and fully functional within a single file (please don't make us reverse-engineer any more sample apps).
4. A step-by-step walk-through of the code, either in the code itself as comments, or in the document.

At some point a more advanced tutorial on best practices and application architecture would be useful as well, but for right now people are still struggling with the basics.

I found way to fix problem with test app:

You need to do next changes in facebookapi_php5_restlib.php replace code:

   if (isset($short_story_template)) {
     $short_story_template = json_encode($short_story_template);
   }

with new code(there was added "s"):

   if (isset($short_story_templates)) {
     $short_story_templates = json_encode($short_story_templates);
   }

AND ALSO replace

 public function &feed_registerTemplateBundle($one_line_story_templates,
                                              $short_story_templates,
                                              $full_story_templates)

with

 public function &feed_registerTemplateBundle($one_line_story_templates,
                                              $short_story_templates,
                                              $full_story_template)
