I think this makes sense. I certainly look at far more pictures and videos on Flickr and YouTube than I upload myself. But I do upload to both. <p>But I think the title is wrong. These ratios seem normal to me, not weak.<p>An interesting number would be word count of read vs. written in blogs and comments. My guess is that bloggers have an easier time having a conversation than videos or photos allow, making it more participatory. <p>And on that same note, do you include comments as participation? I think you should, but it doesn't look like they did.<p>
