Yeah, it all depends on what you think "good" is. I want to say if you get 500+ UNIQUE visitors each day, then you're definitely doing pretty good.
I have two different blogs, both are relatively new. But I think on average
DatMoney.com gets about 150-300 uniques a day. But again, this is my newest blog...
Then there's
DatCurious.com which flactuates but on average probably like 400+ UNIQUES a day. The most I've gotten in one day was like 1,400... which was a shocker to me...
