I've made this decision a long time ago, and today i'm making it again: i'll only have one blog in each language, where everything has to fit ... whatever i want to write about.
Long story short, I've picked two of my blogs with the most posts - i'll only focus on them. The Hungarian blog I have will not be updated, as there's no point. Hungary is very hostile to foreign companies and workers, so it would be very hard to put ads on the blog and actually make some money, while providing readers at least somewhat useful content.
https://stiri-itc.blogspot.ro will be my main blog, as I live in Romania and know this market the most.
https://gr8-dealz.blogspot.com will be my English blog, where I don't expect to make much money, but will write a lot, as I enjoy writing in English more than in any other language.
I will also have a third blog, where I'll only post funny photos, Photoshopped by me (actually I only use MS Paint), maybe a few words for explaining the context... I don't know how that will go ... https://feexed.blogspot.com
