Interesting perspective. Like you, I have also come to adore the platform.
Without question, Medium will change, especially as it seeks profitability. Currently, it is dependent on VC (venture capital), but that money is drying up since most VC firms are expecting a market crash in the next 1-2 years.
My guess is Medium will look drastically different once advertisements are introduced. Mentally, I'm preparing to see a Doritos ad in the middle of one of Tim Denning's stories.
As much as I want to keep Medium as is...it is destined to change, and thus trends will come and go.
Overall, I thought you did a great job with the flow of your story. I thought the use of each section title was conversational. Like it led into the next section, which is unique and made for an enjoyable read!
One suggestion: you may want to double-check for grammar. I noticed a couple of minor missed periods. Personally, I use Grammarly, and I can't say enough good things.
Thank you for sharing!
