I also agreed...this is works as one way link for your website so this will definitely plays some role in ranking.
I think regular commenting on DP is a great way to add inbound links and lots of people make sure they spend some time everyday adding comments.
DP forums site is a good source of backlinks to your site(s) since it is a high-traffic site. I've seen DP pages indexed in Google and other search engines.
Sure it can... But more importantly it actually brings visitors! Which is far more important than rankings.
I feel that it contributes towards the ranking of your website. It also enables the pages to get indexed fast.
i've only put my signature on one day ago and i've already had a lot of visitors from DP... So yeah, it helps with getting visitors
