My two cents
Not every time that you have to share an idea, you need to create a proper presentation. In fact, I would say that roughly:
80% of the time, a quick document like a Notion or Dropbox Paper or Miro is good enough for sharing an idea, a report or a piece of information. And if needed you can always make a short three-minute video in Loom commenting on the document for additional interactivity.
15% of the time, you could create a presentation just using a template or an app like Paste by Wetransfer that makes it quick to create a presentation.
5% of the time, you really need to create something custom and spend hours in choosing the perfect images, perfect words and perfect layout. Think of these presentations like a mini TED talk or pitch to investors.
So most of the time, a simple document is the smartest route: it takes less time for you to create, and get's all the key information shared too. And if you use apps like Notion or Dropbox Paper, your document adapts also perfectly to be read on both a desktop or a smartphone.
I have to admit that I myself still create too many presentations, and want to get better at this, but I'm getting there, and I'm sure you can too. Let's save a few hours this month by creating less fancy presentations!
