Thanks everyone for the advices.

*eastado- I used to submit some articles using article submitter but it didnt seems to work very well. I will try doing it again using the links that you provides.

*projectX- I used to have about 20 visits per click but yesterday I have about 130 visit but only 1 click. Most of the visit came from youtube.

*looreen- I though putting other ads with adsense is a violation of their TOS.

*sikandar- I just changed the theme, it should look nice now.

*oldenstylehats- I claimed my blog with Technorati,now I just need to know how to ping it.
