I'll keep this short since I'm shooting today. I was poking around the Black Blog and found a great entry about building your on-line portfolio.
Here is my favourite point: Put your heart into it. All of it. I find there is a direct relationship between how much heart you put into your book, and the amount of heart you put into everything you do. The more heart, the more likely your portfolio will end up on the "Joy to Review" list.
