First time posting on the site, but have learned a bunch from you guys over the past few weeks.
Here's my question:
Using Scrapebox, I've been able to find a bunch of PR4+ dofollow blogs that are still open for commenting. However, some of these blog entries or threads are from 2010 (obviously, there are recent ones as well). The question is are links placed on these older blog posts and threads as useful as links placed on newer ones?
Thanks in advance for any insight.
