Thanks to the #foaf crowd (Libby and JibberJim in particular) for pointing me in the right directions.

Other notable points in the update, I've sorted out some of the confusion with my Ecademy Foaf file by including my foaf:mbox_sha1sum foaf:homepage and rdfs:seeAlso for this file in my foaf:Person rather than having a seperate foaf:Person for that content; that makes sense when you think about it, it's just more data about me, it's not about another person. I had Mobitopia as a foaf:weblog, sure it's a weblog I contribute to, but it's not just mine, so I added a foaf:Group which has a weblog (Mobitopia) and a number of foaf:members, and because of this I've also added most of the Mobitopia contributors to my Foaf.

A few useful pointers from this exercise, Jim's files of bad Foaf helped me spot a few errors, and the W3C's RDF Validator and Libby's Rosco tool helped me fix the worst of my stupidity...

The infamous Foaf Explorer and the RDF Photo codepiction tools were useful for surfing the ever increasing Foaf World, apparantly I'm less than 15 links removed from JFK somehow.

Note: If you're one of the handful of people linking to my Foaf, please check your content, there's a few people out there with the wrong details for various things! There's a simple summary of stuff I'd like you to carry in a comment at the top of my Foaf file.
