I've recently (as of less than an hour ago) updated my portfolio site from being a multi-page site to a single page with the reason being I felt I didn't have enough content to warrant the extra space after a lot of thought. I then began wondering if there is an industry standard. I've seen my fair share of portfolio sites but I can't say for sure which layout I've seen most.

What are your thoughts? - Do you have a portfolio site with a few pages or single? Why is that?
