Hi Jimmy
The straight answer is - yes! I have about 12 Blogger blogs and they all make money.
You need to get into promoting them in addition to writing them; that involves building links to them from other sites. There are plenty of ways to do that including what you are now doing i.e. forum posting.
Here are a few ways ...
Forum Posting
Blog Commenting
Article Submission
Press Releases
Reciprocal Linking
Directory Submissions
Social Bookmarking
Good luck!
