Hello Ranier,
Blogs and travelogues are indeed always public when you publish them.
It is also true that you can only find the blogs or travelogues if you have the url or if you look at someone's profile page and then click on "Blogs".
The reader will indeed have to regularly check whether there is an update.
I always make the travel story afterwards and then share the url on my website : https://www.mrmra.com/blogs.phtml
The website will be tackled this year, as soon as the new app is in production.
In any case, I will take it with me when the website is tackled.
