Sure! it's better than $0 per day which is what i had the first several weeks. keep building your content and backlinks and before you know it you'll double your income!
Any money is better than none. Now you have to get more traffic to your site. Maybe increase clicks on ads and work on site to make more money. I also think Everyone whould have a affiliate porgram for the site besides adsense. You can make more money if you get right one for your site. You make 8 cents now try to make 25 cents. Then try to make $1 a day and more the next time.
Like Tearabite and rcj662 said...8 cents is better than nothing. Work hard and your income will grow. $1.00 a day, $5.00, $10.00, and more. Keep giving yourself goals to achieve.
Keep waching these forums regularly, lots of people learned here and earning quite handsome income from adsense and other programs as well..
