I stumbled upon this cool website called about.me which is near enough a digital business card. I really liked the idea of having this single page website to link together all of your different pages across the internet so I signed up to it.
Basically youre supposed to put a huge image on (preferably of you or relevant to you) as the background, and then there is a box for you to put who you are, and what you do, below that there are a load of icons which you can have linking to your various sites and pages.

Obviously this has nothing to do with a main website for a professional but I just thought it was a cool thing to tie everything together.
