I have pages on various networking sites, both personal & professional, that you can check out.

My Flickr - I post personal photo’s, examples of work and any other photo’s I take here.
My Twitter -Short quick updates from my Twitter page. The most up to date, but usually the most pointless!

MySpace - I rarely use or update my MySpace, I only have it so people can find me there. You can find my friends there too.
Facebook -As above really.

Behance - This is where I keep a public portfolio of any projects I do. It’s a great site for designers, if you haven’t seen it before get over there now.
Compulove - Not as widely used as Behance but still a nice creative networking site.
Humblevoice - Again, not as popular as Behance but a good resource.
LinkedIn - This less about the work I do and more about making connections, again you can view my friends and contacts here.
