In advance of the conference ask every speaker and panelist to send you two tips, under 100 words each, with a title that is five words or less, with apt embedded links in the text, a one line bio with up to three links and an image to go with the tips and a head and shoulders photo of the contributor.
This means there has to be a deep-level screening of all content on that web page, including text, images, banner ads, clickable links, audio or video files, etc.
