Francesco,
We don't have a definitive timeline yet on when automatic pushing of content will be available. It will be in either the 6.3 or 6.4 release, and major releases usually come out about every 3-4 months. The 6.2 release came out in late September, so 6.3 is in development now. If the automatic pushing of content can be finished, tested, and up to our requirements for quality, it will be in that release around the end of the year. If not, it will have to wait until 6.4.
The issues with auto-posting are many:
* We have to know the details of every extension that needs to auto-post. Obviously, we'd support Joomla content, but other extensions would need support through a yet-to-be-developed plugin system to know how/when content is created
* Automatic posting can have lots of issues with the URL structure of Joomla since there are usually many URLs to access one piece of content. Knowing how to create the best URL is a real pain.
* That's the biggest issues, but there's underlying issues as well.
Even when we implement auto-posting, we'll still recommend using the auto-method since you'll be able to time the post properly, add a comment, and be sure the URL is correct.
I hope that helps explain everything, but if you have any questions, just let me know.
Thanks,
Alex
