To anybody, when looking at somebody's blog they can say, "this is crap" or "i love this." So when thinking about what makes a good blog, I would say it's hard to pinpoint the exact things that make a good blog for everyone to enjoy, because, everyone is different and has different views on what they like and don't like. Let's take my side, for example:

• I like to view pictures. If it pertains to what you're talking about, share it so we can get a visual. The more the better (but not too many so it drowns out the text...)
• Don't overcrowd the page with words. I will automatically click to the next page or skim through it briefly
• Be creative. Don't use technical terms and try to sound smarter than you are. Write like you are talking to me, in a casual, sarcastic sometimes, tone. I don't want to feel like I'm reading a textbook. I've had enough of that.
• I, personally, like reading what people would call, more like journals. It's what keeps me interested. I love gossip. Celebrity or not. And it doesn't necessarily have to be gossip. I like knowing how other people feel and what is going on in their lives. ( is that nosey? oh well...) But please, keep it on a happy or semi-happy tone. I don't want to read somebody's suicide note or anything.
• And...I don't know, a nice background is nice. Crazy anime's like one website I saw is not cool though. Neon bright colors swirling all over the place like one friend of mine has= not cool also. It hurts my eyes too much. I don't want to have to put sunglasses on to read your blog.

And with that, you have my criteria for good blog posting. For you it may be different, but this is what I like.
