Is it always hard to get the first instructional Designer job? For discussion and advice

Personally, I think both options are good ways to host a portfolio. A website may offer more layout customization, but typically takes longer to build. A Rise 360 course tends to have fewer layout options, but they're all responsive (so they'll look great on any device) and fast to put together. Also, while websites are still what a lot of people use to create portfolios, Rise 360 portfolios are growing in popularity, You can see several examples of them in this portfolio E-Learning Challenge. So it's really up to you to decide which option you like best and you have the capacity to produce.

What's more important than the way you host your portfolio is the content in it. Given you're looking for work now, it may be best to stick with your Rise 360 course since you've already started it and build out the content there. That's the fastest way to improve your portfolio. And there's no reason you couldn't move all that updated content to a portfolio website if at some point in the future you want to make that change.
