Issues with Reading

I've read books since around age six. It is a necessary skill many people are still lacking, so I was very lucky. Now I need ever stronger bifocals to keep reading and I have some macular degeneration. It is a sad state, but I'll still keep reading for as long as I can. If my vision gives out, I can still listen to audiobooks.  Few people can spend all day, every day, or even only free time, reading. 

Reading makes better writers and good writing makes good reading. Author use techniques to ensnare the reader and keep them interested in the story or topic. They keep everything in a logical order with wording that smoothly leads the reader through all the pages to the conclusion, but glitches happen.

The following issues often put me off reading:

Nonfiction:

• Go-on-forever articles that are full of rambling off-topic opinions.
• Articles with many unfamiliar and undefined scientific words and acronyms.
• Must-reads required for work or any other function.
• Legalize language in any form or content, especially in small type with little space between lines. Done purposefully I'm sure so the reader isn't inclined to read the information. Is it impossible to put important legal information someone must know into an accessible, fast-reading format?

Fiction:

• Reading stories with characters I dislike, which is usually because of their moral viewpoint. These are the main characters, not secondary or incidental ones. If they are lying cheats I have to know right away what caused this and what mission they are on. If the character has a major turnabout in viewpoint, attitude, or behavior, then okay. However, I sometimes doubt these changes are anything more than to get their own way, so the cause of the turnabout is important.
• Snarky first-person voices using metaphors to make the reader laugh where I'm completely ignorant of the meaning. Am I behind on cultural jargon?
• Stories with too many characters. Yes, I'm guilty of writing some, especially in series novels. Most, however, are minor characters. Usually, I keep the main characters to four, and secondary characters to under ten. One novel, Crewkin, had seven characters total until the last chapter.
• Knowing which character is which bothers me when the names are so close in spelling or sound very similar. I am always mixing them up. This happens often in fantasy novels with Gaelic names. I read one with five Gaelic names beginning with A. I couldn't keep any of them straight but learned the valuable lesson of watching my own characters' names spelling and pronunciation. Isn't it funny how the words sound in our minds as we read?
• And finally, stories starting with issues listed in the previous round-robin post, What draws you into a story.
