I just signed up for a subscription with Majestic SEO at the silver level this morning (like, 1:30 in the morning), since it APPEARS that they have many more links to my competitors indexed in their database than does Open Site Explorer.
So I will have to try building some reports and let everyone know.
I use scrapebox to try and find potential link partners, but scrapebox needs to use proxy servers so you don't get banned by google, and getting decent proxy servers is getting harder and harder.
SEO Spyglass used to rely on Yahoo Site Explorer for their database of links. Now they say they are using a new database. I don't know where they get their links from, but would love to hear if someone else has used it lately.
