Questions for Blogger

Two days ago i came to Extension Information Technology Showcase in Iowa State University at Ames. A lot of things happen and interested me. One of them was when i took the meeting about blogging. Yup, blogging, blogger and blog. Three words that was really familiar with me today and the day after and before....

When i followed that meeting, the speaker told us about blogging and related to that. One of interested me was about questions for blogger and i wrote it down so i can ask you about it. Here are the questions and i hope you can answer it honestly :

1. why are blog popular?
2. who is your audience?
3. what is your personal goal in what you write?
4. what is the goal of the blog?
5. how do you decide what to write about?
6. how do you remain relevant?
7. how do you show your authenticity, your authority?
8. share some do's and don'ts you have learned the hard way?

So? what do you think about it guys? for me it's a good questions and we can ask it by ourself, why we became blogger. is just for fun or for killing time or....what??
