Interesting, I've actually gone in the opposite direction.
I now write posts in a Google doc first, then I copy that over to where I'm going to post that (either Substack, which then gets imported to LessWrong, or LessWrong directly).
Reasons for doing that:
Plus then I have an extra backup should anything happen to LessWrong or Substack.
I'm not sure why I didn't do this before, but I just tried and I don't like it quite as much:
I was pleasantly surprised that copying images from Google Docs works though.
I imagine for people with more general posting goals this would be a good idea, but since the only two outputs I care about are LessWrong and Markdown, using the LessWrong editor works better for me.
I don't need a backup on Google Docs since I use my personal site for that (the content is all on GitHub + several of my computers).
Better spellcheck would be nice, but I just run my posts through an AI before posting and it seems to work pretty well.
Ah, right. I'm opposed to footnotes, so I don't use them, and I rarely use image captions, preferring to address any images directly in the text. Those would change the calculus, though, if I wanted them.
My personal website has been using a Markdown-based static site generator for years, since I wanted something easy (and cheap[1]) and wanted to ensure that I wasn't tied to any particular piece of software. The one downside is that I have to write files into a git repo, so it's pretty hard to write posts when I'm not at my computer, and the trivial inconvenience prevents me from writing as much as I want.
Enter: The LessWrong editor. This has several features that have helped me write a lot more on my phone:
Being able to drag-and-drop images is really nice when editing on a computer, although I can't seem to get the ¶ symbol menu to work on my phone, so I do need to go on my computer to finish images. Having a post completely planned out still makes that much easier.
It's also nice that I can post to LessWrong, then do the conversion when I get around to it, including retroactively turning a post into a linkpost (for the canonical URL cred[2]).
For example, I wrote this post on LessWrong, then copied it to my personal site, then shared it on Hacker News, and I likely wouldn't have done either of the later things if I didn't have a nice editor to make the first version.
So, thanks for the Lightcone team for making such a nice editor and letting me abuse the site's tooling like this. I credit this for at least half of why I started writing a lot more in the last month or so. Getting feedback from Justis on some of my earlier posts also helped a lot with my confidence.
I paid Amazon 56 cents last month to host my website using S3 + CloudFront.
Although looking at the source for this article, it looks like LessWrong doesn't set canonical URL's for link posts correctly?
This process is still kind-of annoying, since Markdown doesn't have a way to say that an image is a caption, so I have to re-style captions on my site; plus I don't want to hotlink all of the images so I have to add them to my site and change the links.
Finding the motivation to convert an already-successful post is much easier than finding the motivation to write a post from scratch though.
