The author Jeff Goins has built a brand off of challenging his followers to write 500 words a day. Doesn't matter what they are or if you publish them, just write 500 words a day. The principle behind doing so is to prime the creativity pump.
Julia Cameron is known for author pages which is starting each day by writing (by hand) 3 pages. Again doesn't matter what, just put the words on paper. Same principle.
I have found when I write more consistently that my words do flow more. But then, I've usually found once I have read or made enough notes to get started on writing the words, I can hit 1000 words in 30 minutes or so. It's getting the thought process flowing that takes me time.
Then having written 1000 words, I spend the next 30 minutes chopping the extra language out of my writing. The writer's version of 2 steps forward, 3 steps back except we end up with tighter, cleaner writing.
Wow, 60 minutes only? for 1k words? The 3 hours I mentioned, is from zero to publication, which usually includes an image I create, the formatting, the publication itself. Not sure what time I usually take for 'just' the writing. Maybe 60min instead of your 30min? Maybe a little less, or even more? Need to time it next time 🙃
I have the experience with long-form comments, I write quicker; I suppose writing a comment is easier to write an interesting post.
Jeff and Julia: Both interesting concepts! A few years ago when I was writing more frequent, I believe I was more creative. Yesterday I was saying this to a friend when reading some of my old posts of 4+ years ago. So, they may be right in what the claim 😉
