Become a better blogger

What does it take to be a good blogger?
Good question, but good answers would be more helpful.
 I had a look at some blogs and I think I came up with some useful answers that will help me (and maybe some of you as well) to become a better blogger.

• It's nice when people write about things they're passionate about and really put a lot of time in it to make it perfect, but if it takes the reader half an hour to read ONE post, you've failed as a good blogger. The reader neither wants to get bored when reading nor to drown in information. Especially when writing about a trip, keep it short, but interesting. The reader's eye will be more thankful for short paragraphs than long text passages. 
• When you now think: "But hey, they're so many things I want to say about this topic because I'm an expert and have so much experience in blabla I need to share with the world so they know how much I like it and maybe like it too.." Don't. If you want to share your experience, knowledge or thoughts in a good way, the length is not important. What really matters is HOW you write about it. The reader can tell by the words you use if you know a lot about about it, if you like or hate the topic you're writing about.
• So that's how you write: Grab the reader's attention with rhetorical questions, catchy titles, write in a witty, humorous way that makes the reader laugh and don't write too general, let them know your opinion. Create your own unique style that everyone makes reading YOUR blog, not anyone else's.
• Highlight certain words or sentences! Not only I likes to skim through a text to decide if it's worth reading or not.
• Don't use too many technical terms, at least not without explaining what you mean. You might want to show off with your knowledge to be cool, but your readers will hate you for googling everything. If they even make an effort to google, they might also stop reading.
• Add a lot of pictures, readers LOVE pictures.

          And cats. Because we all know that cats have won the internet.

I'm not sure if I can use all those helpful tips, but will at least try maintain a humorous style that make my readers laugh and keep reading.
I won't write too short and too long and I will try to write good blog post without spending hours of rewriting to make it perfect.
Maybe I'll leave out the cat thing...
