The Open Thread is a general discussion forum, where you can talk about whatever you like — there is nothing ‘off topic’ here — within reason (see Note below). So get up on your soap box! The standard commenting rules of courtesy apply, and at the very least your chat should relate to the general content of this blog.
The sort of things that belong on this thread include general enquiries, soapbox philosophy, meandering trains of argument that move dynamically from one point of contention to another, and so on — as long as the comments adhere to the broad BNC themes of sustainable energy, climate change mitigation and policy, energy security, climate impacts, etc.
You can also find this thread by clicking on the Open Thread category on the cascading menu under the “Home” tab.
Note: This is a new general Open Thread. However, two more specific Open Threads are also still available: (i) if you wish to make a philosophical comment on the Fukushima Nuclear crisis, go here; (ii) for technical comments on the Fukushima situation, go here. Every other non-post-specific comment can go below. For reference, the last general open thread (from 20 February 2011) was here.
