Yes you are absolutely right that these social bookmarking sites are very important to get boost for a website and for social media promotion but there is need to build a community on these sites.
I think it would depend on which type of community you're targeting. Well, you've mentioned the general ones, but I saw deviantArt in one of the replies here. Well, there are forums in dA, but most of the people there are artists. If you're looking to sell stuff there, it would be okay, but the chances would be low. I'm not saying that you should completely ignore it. You should still join because social media is supposed to be a way for you to create relationships.
Yes, community building or creating groups will be more helpful. The more engagement your profile on social media will have, the more social signals your site will get on Google SERP hence rank improvement.
