Pat A asked "In addition to the 50kb rule (based on download speeds), we used to be told the best pages should require no more than 5 scroll downs. How does this convert to the mobile world? Are 50 too many -- or do mobile users not mind flicking the screen repeatedly? Or do they not even search for and read these kind of pages? Thoughts?" For a mobile user, one scroll-down might be too many. I guess it depends on site content, how badly the viewer wants it and competition for attention. IMHO, subject matter rules! If the content needs a longer page, it should have it. 'Course, I'm biased toward the user who will invest effort for the content. All my sites are about complicated niche subjects: genealogy, genetic genealogy, sailing tactics & strategy. If the materials were readily available elsewhere, there'd be no reason for the sites. Plus, I'm not trying to get money; the viewers' only payment for what's offered is their time. These pages require text, tables, diagrams, pictures and graphs. They tend to get fairly big. An example is http://taylorfamilygenes.info/haplogroups.shtml, explaining human Y-chromosome and mitochondrial DNA haplogroups and how they relate to each other. I doubt such a page can be easily adapted for iphone or Android viewing. It seems to me that mobile apps deal mostly in relatively simple content, although the technology behind the display can be very sophisticated. In short, there are pages for "click and go" use and others for "stick around a while and learn something". Different purposes, different standards. -rt_/)
