LL has laid off 30% of its employees, and some are saying more layoffs are coming. The virtual village idiot is busy gloating, while others mourn.
Some fear the end is near, others look forward to SL access via the web. (If Hamlet's right, that will happen via WebGL, a way for web pages to get to OpenGL, so this does not necessarily mean smartphones and netbooks will be able to get to SL.)
All I can say is, thank goodness for OpenSim. One of the virtues of Open Source is that you're not held hostage by a sole source, and if worse comes to worst I think we'll appreciate that greatly.
