3 . Google XML Sitemaps

This plugin will create a Google sitemaps compliant XML-Sitemap of your WordPress blog. It supports all of the WordPress generated pages as well as custom ones. Everytime you edit or create a post, your sitemap is updated and all major search engines that support the sitemap protocol, like ASK.com, Google, MSN Search and YAHOO, are notified about the update.

4 . SexyBookmarks

Though the name may be a little “edgy” for some, SexyBookmarks has proven time and time again to be an extremely useful and successful tool in getting your readers to actually submit your articles to numerous social bookmarking sites. Our sole aim was to stray away from the “in the box” thinking behind most social bookmarking plugins, and add a little flair that would entice your readers, rather than deterring them with microscopic icons that get lost in pages heavy laden with content.

5 . WP Super Cache

This plugin generates static html files from your dynamic WordPress blog. After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.

The static html files will be served to the vast majority of your users, but because a user’s details are displayed in the comment form after they leave a comment those requests are handled by PHP. Static files are served to:

  1. Users who are not logged in.
  2. Users who have not left a comment on your blog.
  3. Or users who have not viewed a password protected post.

99% of your visitors will be served static html files. Those users who don’t see the static files will still benefit because they will see regular WP-Cache cached files and your server won’t be as busy as before. This plugin will help your server cope with a front page appearance on digg.com or other social networking site.

6 . Conversador

Chat with a fictitious character that learns from you. The bot records all the conversations and uses the users answers to write. When you answer a question it memorize the relation between both phrases, so if someone do the same question, it will write a related answer.

7 . Third Party Host Fix

Fixes WordPress’ inability to find the install directory when it’s not in the root folder. This includes hosting services such as 5Gigs and Bytehost. This is a plugin workaround of the “Cannot find Content directory (WP-Content)” or “Unable to locate WordPress Root directory. Installation Failed” errors to get the following built in features working : Plugin Installation, Theme Installation and WordPress AutoUpdate.

8 . Better RSS Widget

Replaces the built in RSS Widget and adds the option to select the link target.

  • Allows multiple widgets each with different settings.
  • Adds the link target to both the RSS Title and all articles.
  • Default settings screen allows you to decide what defaults will appear when adding a new widget.

9 . Add to Any: Share/Bookmark/Email Button

Help readers share, save, bookmark, and email your posts and pages using any service, such as Facebook, Twitter, Digg, Delicious, and over 100 more social bookmarking and sharing sites. The button comes with AddToAny’s customizable Smart Menu, which places the services visitors use at the top of the menu, based on each visitor’s browsing history.

The E-mail tab makes it easy to share via Google Mail, Yahoo! Mail, Hotmail, AOL, and any other web-based e-mailer or desktop program. The Add to Favorites button (or Bookmark tab) helps users bookmark using any browser (Internet Explorer, Firefox, Chrome, Safari, Opera, etc.).

Individual service icons let you optimize your blog posts for specific social sites. Choose from over 100 individual services.

  • AddToAny Smart Menu
  • Individual service links (like Sociable)
  • Includes all services
  • Menu updated automatically
  • WordPress optimized, localized (English, Chinese, Spanish, Portuguese, Italian, Danish, Catalan, Russian, Belarusian)
  • Google Analytics integration

10 . WPtouch iPhone Theme
