I have waaaay too many saved articles in my Instapaper account.
In the next few weeks I’m going to be cleaning this shit out and posting anything that still rings true to me. This is the great thing about truly great insights and knowledge—it doesn’t have an expiration date.
Here’s a great post by Seth Godin from 2011 I found on tips for making a great Powerpoint presentation:

The typical person speaks 10 or 12 sentences a minute.

The atomic method requires you to create a slide for each sentence. For a five minute talk, that’s 50 slides.

Each slide must have either a single word, a single image or a single idea.
I’ve worked at too many companies and seen too many presentations that try to cram in as much information onto a slide as possible. Don’t do that shit. Instead, provide printed out notes (aka, a “leave-behind”), if you need a more in-depth explanation of what you’re presenting.
