@LinkPopularity: How do you define not seo-friendly directory? You are not talking about the SEO friendly URLs. Are you? Because google (if not other SEs) can surely index those directories (and you can see the number of pages indexed).
All directories have dofollow links and thus are seo-friendly. I remove directories that become nofollow regularly.
The popular saying is any free directory can become paid or link farm. So I keep an eye on that too. But this is under no circumstances a perfect list. I have given the relevant data that people can use to decide whether the directory is good enough.
For example a PR5 with 0 pages indexed would probably mean fake PR
