Well if you want technorati to capture your posts, events or reviews then you must make sure your content is microformats enabled. Many tools and services do this automatically so you may already be done with this step! WordPress is one of them which is already microformats enabled (LinkRoll and XFN properties). Some implementations are here at microformats.org wiki . You can have a look how you can implement the microformats. Once your topics, posts, reviews are microformat enabled then you can start pinging technorati to start collecting to your site. If you publish microformats somewhere that is not a blog (e.g. an "about" page, an events calendar, or a reviews site), ping Pingerati with the URL.

WordPress has XFN support built-in to its Link Manager function, which is used for generating blogrolls. When in the administrative interface, choose the Links top-level menu item, then choose Add Link. The link form lets you choose which XFN properties you wish the link to have. When displaying the links on the site via any of the standard WordPress template tags, it will automatically format it with the appropriate tags in the rel attribute.
