Well, i did that all my life. And at some point i started a small blog. In 2009 if i remember well. But i don't know how to market myself and that one being as a blog also for me to find again the info that i need (with full details about solutions) i wrote from time to time.
Now when crypto world opened the road to steemit, i try to do the same. With all the things i know and i have time to share.
I would love to have this as a main job... but i don't think is possible for me now. So, i write from time to time.
Cheers
