Reddit is one of the most popular sites on the Internet for discussion of news, politics, technology, science and a whole host of other topics, and the site labels itself as ‘the front page of the internet’. I have seen a few discussions about LENR on there in the past, and I have myself posted about it once in a while. I have just been informed that there is an LENR ‘subreddit‘, which is basically a dedicated space for the discussion of LENR, and it can be found here: http://www.reddit.com/r/LENR/
Facebook also has some spots where people talk about LENR. The most popular group which has nearly 900 members is named ‘Cold Fusion, LENR and Andrea Rossi‘, and I have just joined another smaller Facebook group titled ‘Peak oil, cold fusion and the future of energy’.
The Reddit page isn’t very active currently — there is more activity and comment on Facebook at the moment. But I have to say that those of us who are interested in LENR are still a relatively very small subset of the larger online population. Right now as we wait for further news on the E-Cat and other fronts, there doesn’t seem to be much impetus for rapid growth of interest in the field, but I think with positive results from the E-Cat testing team there is a potential for a much wider discussion of the topic, and we might find lots of new people joining the online discussion.
