I just figured that I'd talk about studio's social media presence.
First off, we have our own forums. One for the compilers and one for the tools. This is a good place to post comments and questions; posting here will get our attention.
We also have a presence on Facebook and Twitter.
Moving to the broader Oracle community, these pages list social media presence for a number of products.
Looking at Oracle blogs, the first stop probably has to be the entertaining The OTN Garage. It's also probably useful to browse the blogs by keywords, for example here's posts tagged with Solaris.
