What data about users and how they use your website do you wish you could collect?
showerst: <begin brain dump>
I've never really seen a good visualization of a site's link graph (with focus on link text & page rank), probably due to the sheer size of many sites.I'll second other posters that time on site for each page is a biggie.Anything you can do to expand on the 'funnel' model is solid. (Clicktracks treatment of this is especially good IMHO)Just to throw it out, I'd love to know more about if/how my users use other sites (so i could see if they've been on competitor.com or wherever recently =P), Although I can't possibly think of a way to do this that isn't a blatant privacy violation.I'd also like more clustering options by language or country, so i could see if US/English users use the site differently than UKers or German speakers, although I realize that for most sites that are international enough to care, they have multiple language sites, there's still visitor cross-over.This is a stupid one, but automatic FTP downloading of log files is something I seem to have to set up all the time, so a mechanism for aggregating logs would be nice =).All just random brain noise, hope it helps =).
