If you want good traffic, exchange won't help you cos' you're just too small now. You can promote your site on forums but you can get banned there pretty soon. Do it as others, invest few $ to start faster.
, for about 3$ you got 1000 visitors, +0,5$ more you have USA,EU,CA traffic only. Trafficholder got tons of different niches - for example you can choose "teen pics" traffic only what probably suits your blog best & traffic is much more effective. ENJOY. Wish you high earnings.
