Perhaps some brainstorming would be useful:
(1) Dr. Swamidas, have you had any experience with venues like TED Talks™ and TEDx talks?
Even just one video on Youtube with a click-baiting title like “No, Science hasn’t ruled out Adam & Eve!” or “A scientist says that the Biblical Adam really could be your ancestor.” might greatly increase your traffic and thereby lead people to check out the PeacefulScience.org forum.
(2) Some film/video students are looking for projects in which to develop their skills (and even get course credit.) A student documentary-maker could weave together segments from your current inventory of video lectures and debates and interweave it with segments about your research and daily work regimen. Also, new videos of about six to ten minutes in each installment (extracted from existing videos) released every few weeks would help build up subscribers on your channel. (Bite-size topics are important. That is why your ASA lecture you recently linked was so outstanding. It focused narrowly and simply and gave most of the time to questions.)
(3) Public challenges posted as brief videos to Fuz Rana and Dennis Venema and Scot McKnight could definitely draw a lot of clicks on Youtube. I think that they would get publicity.
(4) All of the above are likely to get more bloggers discussing and linking to your webpages/channels.
(5) There may also be college students in P.R. related fields who need projects for their portfolio. I understand that “social media management” has become a career choice for a lot of business school students.
All of the above ideas have their drawbacks and pitfalls but it all comes with brainstorming.
