I think I can explain, because it bothers me too.
If you create an blog and make it public, this doesn't work any longer! No one is able to find this blog!
Since the new SW for the forum is in place, the old blog can't be reached any longer for other readers. But the new forum has the new category: "Travel stories". Only this category can be reached by other readers.
Unfortunatelly, this new category "Travel stories" doesn't have the same functionality as the old section "Blog"!
I can imagine - users, which are riding just Sunday afternoon - will/can write nice interesting stories. But longterm traveler like me will/can write a lot. And it's great to find everything you need for a long journey in one and the same app!
This will may be also helpful for others, which intend to travel to the same region, and are going to gather more information.
The section "Blog" is very important, because it's one of the USP (unique selling point) of the app. There are a lot other route planning apps on the market (which don'thave this). I fear, if MyRoute-App Team will reduce functionalities of the App, potential users may go away and purchase another app.
