Basically, like Digg and StumpleUpon, Mixx is a social bookmarking website. It aims to provide you with links to the web
content that really
matters. There are a lot of
information out there in the virtual world of unlimited information and it is something sad to say that not all really matters or important. The business model of Mixx is practically for the users of this site to submit what they think to matters and important which in terms will generate quality links to web resources.
My opinion on Mixx is very positive because it really works when it comes to bringing traffic to submitted sites. Of course, I am not advocating that everyone should submit their own content, but I do not see anything wrong about it either as long as they are not abusive and insulting in nature.
Do give this social bookmarking website a try and you will know how well it works.
