Has anyone ever use this directory? They seem to be pretty good, I am somewhat waiting to see what happens with there pr.
It's been around, AFAIK, since mid-2005. The concept behind the directory was to not use site titles as the keyword anchor but to put this within the description, surrounded by other content/keywords/relevant phrasing. The owner, Mark Steadham, also runs Octopedia (or did last time I spoke to him).
It will give you some boost, but wont help you with the PR, at least not in the way I am sure u are waiting for .
