Yet another site that I use regularly for blog promotion is Blogsoldiers. This site was recently sold to a new owner and I really like what the new owners being doing to promote Blogsoldiers and get more members.
There are regular surfing contests where the top ten surfers win 500 to 100 credits each. Plus the new owner has instigated a bonus system that kicks in as you are surfing sites. I don’t know how many sites you have to surf before the bonus’ credit questions come up but If you are surfing (viewing) sites for an hour you’re bound to get bonus points at least once, if not twice.
The owner of Blogsoldiers send out newsletters every so often announcing new contests and just keeping in touch with the site members. Very few of the other traffic exchanges do this on a regular basis with the exception of Blogazoo.
