Maybe best to break this off into another thread, but I don't believe forums are a dying species. Just this particular forum has lost momentum and I don't see any attempt to revive it. Social media is a different interaction interface. If you've ever tried to use groups on facebook for example, you'll quickly see it doesn't work well for a discussion format like a forum. And twitter is even worse! Of course, it wasn't designed as such and can be more effective used in a different way.
While I'm in this thread, have this pic taken earlier this evening:
Not my best work and I'm not happy with it, but I took too long setting up and cloud killed my chances to refine it. I was simultaneous trying to get the moon with earthshine on it, as well as Venus and Mars nearby. Forecasts suggest there may be more clear skies tomorrow night although they wont be as close together then, and may make better separate subjects.
