I've been writing here long enough to find myself searching for pages I'd written years ago. It is getting easier because I've adopted techniques that make the hunt more effective.
Make your pages easy to remember.
Start every new idea on a new page. Split large pages into smaller ones. Think carefully about what each page is about. Name it accordingly.
Title pages with words you already know and use. Hint at the uniqueness of your ideas by combining words in unusual and provocative ways, but still aligned with the center or source of your idea.
Subtitle each title when used in lists. The subtitle explains the joke or irony in wonderful titles. Subtitles can vary with the context in which they occur.
Write a great synopsis that tells the whole story, not just the setup. Switch to vocabulary that this direct and filled with common search terms. Test your writing with an empty search. Does this summarize everything you have written?
Write where your thoughts make sense.
Write in sites that explain things you know, sites that progress with your work, and sites that catalog what you think and learn.
Let each of your sites develop their own character. If you remember how you wrote it then you will remember where you wrote it.
Don't write in the same place too long. When a site begins to wander, move on. Let the best stuff follow you to new sites where the forks will take you back when needed.
Keep a Roster of where you have written. Load from it when your first search fails to find what you needed.
Write to be read quickly.
Say what will inform your future self as well as other readers. Write simple sentences that make a point. Forget motivation. Forget qualification. Point, then move on.
Establish a rhythm and stick to it. Repeat a few words in place of bullet points. If one point runs long, take words out. You'd be surprised how easy.
Label sections if they mark sides of one idea. Find the one word that informs in the presence of other. Use words that emote, not explain.
Link to one next thing.
Prefer pages that complete a loop over pages that cite each other redundantly. They will be read side by side. Make that a good experience.
Hide external links in a bare link word like 'post' or 'pdf' that finishes a paragraph of explanation. Make clicking these links unnecessary.
Finish a page with a PageFold period if there are going to be stray notes in an epilog. Add these notes when you find them necessary.
Wait until you discover you have revisited a subject to link to your earlier version. Fork that earlier version into the site you write in now.
