As we should all know by now, the success or not of our efforts on the web depends upon how well we can get our results read by the search engines. Get a decent result, high on the listings, and you can make money. Even if money isn't the aim, visibility still matters, otherwise why are we bothering to do this?
In order to gain that visibility some form of marketing is necessary and the old methods really have been tried to death. Which is why this new directory looks so interesting. Based upon Wordpress software they've been very clever in turning the advantages of blogging software into a benefit to a directory. In effect, a Wordpress Directory.
For example, blogging software includes automatic (or semi- at least) pings, which are what tell the search engines that there's new content for them to spider. The traditional directories don't so this, they are simply static and don't tell anyone at all when the underlying sites have changed.
It looks like a very interesting approach and at a mere $3 per entry into the directory I have a feeling that they will be flooded with applications. Might be worth getting your's in now.
