If you want to know who I am, or what I'm like, come buy me a beer and I'll tell you stuff, or you can just look through my usenet posts archived in google which might give you some idea. Online photo albums are often a way people use to get an idea about a person - here's mine - The online photo album of Jim Ley
(a)I work for a UK company e-Media and spend most of my time on a PowerPoint broadcasting service - http://www.showcaster.com/ which allows you to record your PowerPoint Presentation over the phone and broadcast it to people on demand.
What do I actually look like? Search rdf co-depiction data for me, if you really want to know...
I also run, although I'm pretty bad at it - I'm a member of the 26.2 Road Runners Club in Surbiton, Surrey
