I keep a spreadsheet (Google Sheets) of blog post ideas. Spreadsheet columns indicate the following: The date that I had the idea, the topic, which blog it’s for (Medium or my website), the link to what inspired it (if applicable) whether I’ve already begun generating notes, and a column for other comments. I also note when it’s complete.
I generate story notes in Evernote, for the same reason you use Drive/Docs.
P.S. I think that Top Gun references are so ubiquitous that even people who haven’t seen the movie get the reference. (But why is there anyone who has not watched Top Gun?? It has some of the best — read, cheesy — dialogue ever and one of the best soundtracks!)
