Over the years, I have come across several sites around the web which host questions and answers regarding the space elevator. Many of these appear to be essentially fact-free and not worth the time visiting.
I have found an exception, however, and that is the Space Exploration site of the StackExchange network. According to Wikipedia, StackExchange is “… a network of question and answer websites on diverse topics in many different fields, each site covering a specific topic, where questions, answers, and users are subject to a reputation award process. The sites are modeled after Stack Overflow, a forum for computer programming questions that was the original site in this network. The reputation system is designed to allow the sites to be self-moderating.”
I haven’t looked at all the categories of the site (there are a lot of them) but the Q&A discourse for the questions tagged “Space Elevator” at the Space Exploration site seems to be more well-thought-out than at other such sites. If you visit this site, I think you’ll agree…
I currently have three sites listed in my DISCUSSION / NETWORKING GROUPS sidebar category, but am removing all three of them and replacing them with the StackExchange site. The Liftport forums seem to be no more and there hasn’t been a posting in over a year on either the Twitter or the Yahoo Groups forums.
There is an active, ongoing discussion of the space elevator at LinkedIn, but you need to be a member to partake (I’ll add it to the sidebar category too). If anyone is aware of other good space elevator Q&A sites/forums, please let me know so I can add it to this blog’s sidebar.
