Ask HN: How should I organize my portfolio? What should even be in it?

Growing up as a Generation Y, I fell in love with computers at a very early age. Since then, I have accumulated tons and tons of work (personal and for work). These range from running PPC campaigns, social media marketing consultant for hundred-million dollar company, logos/print design, and even a game-hack that I wrote 10 years ago for SC:BW. I was an odd child.

However -- About 75% of them are just simple (but professional) websites that I have made as a freelancer over the more recent years.

1) What would you include in the public portfolio?

I feel that potential clients / employers may like to see that I try to be well-rounded and always curious to try new things. But I'm not sure how others would think about my SC:BW hack called "BagFullOfSh!t" (can't make this up, you can Google "BagFullOfSh!t ghoztcraft" if you're curious lol). Sure, it was 10 years ago when I was 12, but does it deserve a spot -- on my professional portfolio?!

2) How would you organize your portfolio?

I was thinking of putting them into categories, such as "Logo Design," "Website Development", "Social Media Marketing", etc. But a lot of them overlap with eachother. I could also organize it by client instead of project -- but I've worked with some clients more than others. I'd love to hear your input/suggestions/inspiration.

3) What can you include in your portfolio, morally and legally?

For example: I've had the wonderful opportunity to do some social marketing work for the LA Dodgers (just a small project; custom app on Facebook). However, there was a middle-man advertising agency that reached out to me. Morally, I feel that I can post this project in my portfolio, since I did do 100% of the actual work. Legally, however, could it have repercussions on me?

Thanks for bearing with me guys. I learned a lot from my last AskHN thread, and I am deeply thankful. It's hard to have thoughtful discussions like these on Reddit, and I am loving this HN community!
