I checked your site and it looks nice. I also agree with the top 10. But why this PR4 or higher thing...? We have talking about this around here for a while and this will only encourage PR freaks to create spammy directories on crap high pr domains.
you can't install it but you can bookmark it. when you will need this directory that time you will open it and do submissions. there is no any installation process.
You're right. I saw very well maintained PR 3 and even 2 directories that easily can be listed too. fastreplies
Your example site is custom coded, you won't find any copy in the web. You've to develop. Can't understand how Freefind.com listed there as a directory
LOL, you mean these "have nothing to do with directories" web design sites he has on his list? fastreplies
Not only Freefind.com, there are many other site those does not have any relation with directories. Like About.com
I don't own PaidDirectoryList.com anymore, but a nice guy managing this site very well. Recently he added some awesome features!
