Agreed. Thumbar.com is new and has no SEO to offer sites. That can change over time, but that is not the intention. Thumbar.com has no interest in outbound or inbound SEO.
It’s the reverse case: all sites that install a Thumbar get one backlink from Thumbar.com per article that gets rated, since rating an article instantiates a small snippet of itself at Thumbar.com with a backlink to the article at the source site. This can only increase SEO for each site that installs a Thumbar. Just like links at Google.com, links at Thumbar.com direct attention to the source of content.
