Well whether a piece of content is valuable or not ultimately defines your audience (besides yourself through self-esteem).

Do you think there is room for it, or do you suggest I post content that is more about my journey to grow my website.

There is room for everything, since there is an audience for everything. If I were you I'd do some research to find it out - like studying the relevant tags and finding out how many are actually moving within that specific segment.

It's always helpful to check first if there is actually a potential. If there is no niche to conquer, then you might probably keep going and find something else.

I can't tell you what to write about, since I would just tell you what I personally like, and that's not representative at all :-)
