May God bless your efforts!
With blogs, I think the key is to make sure your subject is specific - when blogs have a too diverse range, they tend to peter out because too many other websites are carrying the same content as the blog, and those websites get all the traffic.
Is a blog on Orthodoxy a specific enough subject? Probably not! But being in the Danish language will make it niche enough, and if there really is a lack of Danish language Orthodox content on the Internet, then things should go well.
Stick with the calendar for now, and post lives of the Saints, but also the synaxarion for Feast Days too. That way you can post sermons for the feast days, and saints days where they exist, translating them into Danish if needs be.
Definitely have links to the websites you found useful, but if you found specific writings particularly useful then perhaps you could translate those into Danish first. These could be your "inquirers articles".
Just my thoughts.
