The article says "How many times section can be found in the lower right" under who has viewed your profile. I don't see this? Is it a premium account feature only? Article says it's free...
I'm looking at that page right now and don't see it. I see the chart of views, the text "How many times you appeared in LinkedIn Search", with the total number of hits displayed and the counter showing the weekly change next to (as I can see in your screenshot in the blog). But there is nothing below that.
Very interesting post, LinkedIn SEO is not something you, or at least I, usually think about. Well worth a read for anyone looking for a job right now, or any time in the foreseeable future.
First time I've seen the InMaps feature as well, which is amazing, just love visualizations of social networks.
