Post Often for Technorati Traffic
It seems that one secret to getting a lot of traffic from Technorati and other blog directories is to not post your content all at once. Instead, spread your posts out during the day. Even better, you can experiment with what posting times bring you the most traffic from blog directories.
The logic behind this is that services like Technorati list their search results in a reverse chronological order. So if your blog pings them at the right time, the traffic will come as your site will be near the top.
