Very cool! I have created a few alt accounts with the intention of posting about more niche things but I never actually get around to it. I think it's because I already have too much trouble coming up with things to write about on my main channel.
I have thought about making a photography type account which would be more about things that I learn, as I learn new things; as opposed to showing off photos since I am not a pro or anything.
I totally understand! It's only because my job puts me at a desk all day that I can get away with what I do between the two accounts!
