Today we've added four new 
Google Web
      Elements: 
Sidewiki, 
Checkout, 
Wave and 
Virtual Keyboard. These are all designed to help you quickly and easily
      integrate Google products into your website.
Sidewiki
      element
Google Sidewiki makes it
      easy for visitors of your website to share helpful information with each other. Unlike regular
      comments, all Sidewiki entries are 
ranked by usefulness so that the best ones are shown
      first. The element was built entirely on the 
Sidewiki API and can
      be customized in many ways to fit into your site. Sidewiki originally launched as a feature of
      
Google Toolbar and
      as a 
Chrome extension - this element is our newest step in making
      Sidewiki more open and accessible across the web. If you'll be using the element on your site,
      let us know via 
@googlesidewiki on Twitter!
 If
      you're looking for a way to add commenting to an otherwise static page, the 
Google
      Sidewiki element gives you an easy and simple way to collect and display comments
      about a page. One of the new and exciting features of the Sidewiki element is that it allows
      visitors to leave a comment even if they do not have Sidewiki or Google Toolbar installed.
      Like all Sidewiki entries, the comments in the element will be ranked to show the most useful
      items more prominently.
Checkout
      element
The 
Google Checkout element allows you to quickly and easily create an
      online store using a spreadsheet. Once you have a 
Google Checkout merchant account, you just have
      to add details for each item you're selling into a 
Google Spreadsheet, then use the wizard and
      copy/paste the code into your website. The element is compatible with Blogger, Google Sites,
      iGoogle, and personal websites where HTML can be modified, but doesn't require any programming
      skills or experience. In fact, you can get your first online store up and running in under
      five minutes.
Wave
      element
The 
Google
      Wave element enables you to quickly drop a wave -- a shared workspace -- onto your
      own website. The wave could be used for many different things, including: encouraging
      collaborative discussion among the visitors, or as a means of publishing content on the page.
      For deeper integrations of waves onto your own site, please check out the recently improved
      
Wave Embed API. For more information on embedding waves, see the 
Google Wave Developer Blog
      post.
 Virtual Keyboard
      element
Adding a 
virtual keyboard to your site just got easier with the
      
Google Virtual Keyboard element. After choosing a keyboard
      layout, copy and paste the HTML into your page and voila, a virtual keyboard will be able to
      enter characters into any text input or text area on your page. If you've never heard a
      virtual keyboard, it's an on screen keyboard which translates the input from one keyboard
      layout to another and it allows users to type their own languages on foreign keyboards or by
      clicking the on screen display.
Google Web Elements are great for folks who don't have much time or experience. However,
      even for advanced developers, elements are a great starting point, as most are backed by an
      underlying API to give you even more control over the content or look and feel. Take a look at
      all of the elements at

      stop by our 
help forum if you have any
      questions.
