So this started out as a solution for a problem. The issue I was seeing is when I put together a pitch, either as a PDF or a pages doc, if you wanted to see anything that was linked it would take you out of the document. Whoever was viewing it would have to use two programs at a minimum. Think about this on an iPhone/tablet, it gets super annoying and confusing. Also updating would require sending out another document via email, and more revisions piling up on your computer. So in this madness I was starting to use Squarespace, and noticed two things. One is it's super easy to use, and you could un-list pages, meaning these pages wouldn't show up on your main site, you need specific URL to see the page. So I started using Squarespace as the place for my pitches. This had some great results, one Squarespace automatically formats the page to the device you are viewing on, allows me to update on the fly and quickly, allows me to embed almost anything (I use the google services) and lastly, it sets you apart from others. Did a quick video showing how I use it, I'm sure you guys can think of even more solutions and ideas. Enjoy and let me know if you have any feedback.
(This is a solution that you should be able to do on any website, I just use Squarespace as an example because I love it.)
