The issue your describing is not a scrolling issue but a personal one. The way you scroll cannot encourage anything because it goes in 2 directions up & down. As for hard to get anyones attention it's not people read & either keep reading or ignore.

What anyone feels is important to say will say it but if you go that extra mile to do what you call shouting which is add a pic make extra spacing or spam a icon thats the type of stuff I just scroll right past. Everyone feels what they say is important thats why they say it & one is not less then the other.

Anyways to solve this issue you're experiencing follow the people you like then at the top of the feed where it says global hit that & change it to your follow list. When you find something interesting you want to keep up with follow it & you won't miss anything!
