Just noticed that Stephen Downes emailed me about his implementation of a Javascript-based referrer linkback system. I'd been planning to get around to making one inspired from our blogchat, but he's got it first. Cool. :) Looks like Jon's picked up on it, too.
Jon muses:
I haven't yet looked into what it will take to make the reporting item- rather than page-specific. It's doable, I'm sure. Thanks, Stephen! A ?JavaScript-oriented solution like this will appeal to a lot of Radio users.
The biggest issue I see for Radio, obviously, is that the style there is to have many blog entries on one page for the day. Permalinks are anchors within those pages. However, I haven't seen browsers reporting the post-anchor-hash info for referrals. At first though, one would need to have Radio spew blog entries into individual files to make this JS linkback scheme work at per-entry granularity. Otherwise, I'd love to see this work for Radio. I'd also love to see it woven with community server services.
A few brief musings on the referrers script itself:
get_page_title(). It's a start on what I was musing about over here.
