Delicious.com | Excellent Way to Promote Your Articles
I don't seek for PageRank, since it is not that important for your traffic. Google is not paying much attention on PageRank anymore.
I am just choosing good places to promote no matter if they will or won't bring any traffic. In long term it pays out.
I notice my articles and blogs are moving up in search engines trough time, so I guess backlinking is working.
I would suggest you these places for promotion:
lensroll
chime,
stumpleupon (no-follow but brings traffic),
zujava,
paper.li,
digg,
technorati,
linkedin,
squidoo,
wizzley,
hubpages,
blog,
forums,
EzineArticles...
pinterest (still do-follow if you place link in description)
I use these mostly.
