As you may know, Oracle users of all stripes now have a luxury that few others have: the ability to participate in a social network specifically designed for their interests (Oracle Mix).

The beauty of Oracle Mix is that it's self-organizing; you can create any micro-community of interest that you like. ("Iowa Oracle Users," anyone?) In the past two weeks I have joined groups devoted to JRuby on Oracle and Development Tools, and the OTN Group is expanding daily.

Play with it!
