''Why is it that despite their efforts and desires, that science blogs are unable to capture a more general audience?''
i think judging by here on steemit and from what i see that slowly it captures the general audience. The issue that i try to ''solve'' every time i post a scientific posts is the language to be simple and understanding to everyone. Most people that use steemit do it as something sideways and not full time so they wanna read or see something that can understand ''easily'' and not getting bored.
That's the majority i believe, a majority that enters steemit during their free time in work, or when they are in bus or the night after they come home from their works. They don't need something to tire them with different definitions and many things that they need first to get to understand what the post is about. So once again if we all try to keep it with more simple words i think this will attract more and more people. Ofc on the other hand there are a couple of matters that can be explained with simplistic ways but those posts are primarily for a different audience first an audience that has a knowledge over these things
