Are backlinks from sites like diigo useful for SEO?

[casper434]

I read an SEO article that recommended getting backlinks from social bookmarking sites like diggo.com. Does anyone have any thoughts on the usefulness of these types of links?

I took a look at this site, and while I am not completely finished seeing if there is any value. You can check your analytics / webmaster tools and see if that site refers traffic, brings users, or the link is valuable enough to show up in any number of linkbuilding tools. That being said, any link that is contextually valid, and brings ANY users to your site is a win. Given that DIIGO's deal is to tag and annotate pages it would seem valid as the context is definitely related to the site it will link to. The next question would be are the links follow? can google see, crawl and index the pages?
