I never did something like this, putting myself in the public. It sounds scary. Indeed it was in the beginning, but it's an incredible journey so far!
IE: "My trip to Cabo" might include 1-2 stories out of 10 posted that day, but they are the user's favorite and tell a cohesive story.
Another analogy is Youtube's "Playlist" feature.
I think some will say that you'll lose a sense of discovery by not being on one of the largest video platforms, but you'll gain an opportunity to build something from scratch and see what you can cultivate. It really comes down to your goals/intent, and I think you did a great job of explaining your choice so far!
Also it's interesting to see most of our members never did vlog before. But they still love to share their updates on IndieLog. I think it's because people feel that there are like-minded people around. You can't get the feeling by posting a video on YT.
