WebProNews has a really interesting article about Xomba's new direction. In short, they're making it more of a community site, and creating a business model that relies less on Google searches. After all the hubub about the latest Google algorithm change, a site with a different way of driving traffic is refreshing.
Here's a quote from the article:
"While most content sites rely on Google or search in general for the bulk of their traffic, Xomba’s approach reflects a newer way of thinking throughout the web – that less dependence on search (and being less at the mercy of algorithms) is a better approach for a sustainable business. In other words, it’s best not to put your eggs all in one basket."
For what it's worth, my Xomba earnings have started to rebound more quickly than my other Adsense sources.
