10 blogging mistakes to avoid

Time to avoid the blogging mistake #1 as listed for top 10 (or wost 10?) by John Chow. Of the ones listed, I had never heard of John Chow. How about instead of that # 10, not reading Guy Kawasaki or .. well, keeping fresh and updating your ideas?

And as again, for some own input on the subject, and as continuation of 10 reasons why I've quit reading a blog - here what I could consider some of the worst things for blogging :

1. Being abandoned or giving the feel of being it. If it's about an interesting topic, and has some good content, maybe a look every now and then to check for updates, or maybe it gets to even bloglines or google reader but no new contents in months .. could make a nice graphic here for time per readers abandonment.
2. The God-attitude of writing. "I know everything about cars/digital photography/social networking/social media optimization/photoshop//macs/something else". Good - if you actually do know that much, how about making money out of it and working in that field? Blogging gives good options for a starter for getting good feedback, but if the years of bragging on how good one is is nothing more but confabulation made by just the author, then it may become suddenly boring.
3. Summarized the reasons for quitting reading : no original content, being supposed to like the blog and the topic, buzzwords, blogging about your kids in your work related blog when you are not a nurse, no sense of humor, too much posting or no new content...
4. Poor writing skills. When your language and expressions give the reader a headache, even if it's because of your f4sh10nabl3 sp3ll1ng, still. Let the writing take its time. Formulate the phrases when you know what you want to say.
5. Negativity. People that are negative attract negative things around their life - the life, the work, everything becomes dark and stale. If you don't like negativity, then maybe time to read something more positive than a blog where the constant topics are about how one's life sucks.
6. Not growing. When all your blogging for the past four years have been about one thing only, maybe it's time to add some more interests and write about them. Bruce Schneier doesn't think only about security issues, but also blogs about squids (on Fridays) and writes restaurant reviews. So why would anyone else have only one obsession or interest? Then at least add to your interests getting more interests. Ask your readers for ideas in what to become interested in.
7. Me, me, me. My camera, my opinions, my blog, my links. Me me me. Solution? Get a life, and get some online and offline friends and other interests than you yourself and you.
8. Liking and linking what everyone else does. Google and digg whoring. And just because the boingboing editors like Yasmina Tesanovic or ioerror then you like them just because ..
9. Being afraid of writing or other reasons for no content. It's ok to have as a part your del.icio.us links and quick links to the funny things that you find but add some original input too, at least once every few weeks.

That's 9 until there. What would be the 10th?
Sticking to default template?
Annoying amount of ads?
Using a certain hosting site?
Word is yours.
