Are Links from StumbleUpon Valuable?

Over at WebmasterWorld, users are discussing the potential value of a link from social bookmarking site StumbleUpon. Is it worth trying to submit to or is it completely not worth the effort?

Well, it depends on the content. Is it "worthy of being stumbled?" That's something that you must seek out. Of course, if you choose to take the plunge, the right person might come along and StumbleUpon your page and then blog about it, which can be an incredibly valuable link building experience.

Just a word of caution though: don't use social networks to be overly self-promotional. As one person mentioned in the thread, he was banned for submitting his own content. As a heavy StumbleUpon user myself, there's absolutely nothing wrong with submitting your own content but you must be sure to avoid being self-promotional. In other words, don't only submit your own stuff; mix it with other content as well.

[Note: StumbleUpon links are nofollowed, so from a search engine perspective, it doesn't help much.]
