I dislike Google for pulling the plug on consumer products as well, but this is a product designed for use at Google and I understand they are writing/converting a lot of code in it. So I think you underestimate Google's backing in this case, which is probably the reason Go has seen one of the fastest rises in popularity of any language, ever -- if not the fastest.
Go has made me enjoy programming again -- I find it very freeing not to have to use Java or .NET and memorize 40,000 builtin classes. Yes, Go is similar to Java in terms of its being a "middle of the road" conservative language. But (a)it's conservative for the 21st Century, rather than the 20th, and (b)ditching the virtual machine and bloat of Java is a good thing IMO.
