List of 22 ActionScript 3.0 API’s
Here is a follow up to AS3: APIs” post seen over on the bigspaceship blog last month. The list contains 22 AS3 APIs that should save Flash and Flex developers a ton of time. I have personally used and can recommend the following: Papervision, as3corelib, Tweener, APE and XIFF.

The uicomponents-as3 was a useless inclusion.
No code, no wiki pages, no point in having it in the list…

They are pretty weak, but may be a good source of example code.

I have been using Mock4AS to improve my Unit Tests in AS3. Mock4AS adds Mock Objects capabilities to the unit test libraries (e.g. flexunit).

The Twitter API … is just links to the plain blog and I can’t find any trace of it. Do you know where it is?
Oh by the way Twitter + as3 don’t seem to be the best of friends, where are the examples? Ugh.

The Twitter API is being carried on by a righteous dude here: http://fupeg.blogspot.com/2008/04/twitter-api-in-actionscript.html
Also I can’t believe Twitter would drop the as3 ball like that. Bad Twitter *smacks the Twitter birds, they drop the whale and Twitter dies*
