Your Linkedin profile

I'm not sure why more people don't do this. It's the most concentrated way to see how connected and involved you are in business and networking. Get your contacts to write you good recommendations first, if possible.

Your reading list

Delicious Library (Mac), Libra (Windows), and LibraryThing are all good for this. With the desktop apps you'll need to publish your library to your own site. Don't forget to add any relevant Audible books too. This shows how interested you are in learning, and can provide potential employers with insight into other skills you may have outside of the job you are applying for.

Your blogroll

Same idea as the reading list. If you're a programmer, you should at least be reading Joel on Software, Coding Horror, The Daily WTF, and Signal vs. Noise. Find some well-known specialist blogs in your field and add them to your favorite feed reader (Google Reader, NetNewsWire). It's good for you anyway.

Your social bookmark profile

Think Ma.gnolia or Del.icio.us. Same idea as the reading list, except it shows a potential employer what kinds of things you care about enough to want to refer to later. It's all about involvement. Be careful that you mark private anything you wouldn't want a potential employer to see.

Open-source projects

If you haven't contributed to any, start now. Not only is it good for your own skills, it shows potential employers that you're passionate about coding. If you're not a programmer, you can get the same effect by volunteering.

The overarching theme here is that you want to show that you're deeply involved in your field and improving your skills, and the best way to do that is to actually do it. If you're having trouble getting hired at the salary level or position you want, it might be time to start building up your base skills and increasing your involvement in your field.

Now, do like Daniel-san and start painting the fence.
