  &lt;p&gt;Fortunately, it doesn't cost an arm and a leg to get started building out your own Web 2.0 toolkit because there are free, open-source Web 2.0 applications that enable you to operate your own Web 2.0 services - for fun or for business.&lt;/p&gt;
  &lt;p&gt;Here are 5 of them:&lt;/p&gt;
  &lt;ul&gt;
    &lt;li&gt;
      &lt;a href="http://chyrp.net/ "&gt;
        &lt;strong&gt;Chyrp&lt;/strong&gt;
      &lt;/a&gt;is a lightweight open source blogging application modeled after &lt;a href="http://www.tumblr.com/"&gt;&lt;strong&gt;Tumblr&lt;/strong&gt;&lt;/a&gt;.&lt;br /&gt;&lt;br /&gt;
    &#160;&lt;/li&gt;
    &lt;li&gt;
      &lt;a href="http://elgg.org/"&gt;
        &lt;strong&gt;Elgg&lt;/strong&gt;
      &lt;/a&gt;is a social networking platform. Although I haven't yet tried it out, it looks very promising and it just had its 1.0 release.&lt;br /&gt;&lt;br /&gt;
    &#160;&lt;/li&gt;
    &lt;li&gt;
      &lt;a href="http://www.mediawiki.org/"&gt;
        &lt;strong&gt;MediaWiki&lt;/strong&gt;
      &lt;/a&gt;is the wiki software that was originally developed for Wikipedia.&lt;br /&gt;&lt;br /&gt;
    &#160;&lt;/li&gt;
    &lt;li&gt;
      &lt;a href="http://www.pligg.com/"&gt;
        &lt;strong&gt;Pligg&lt;/strong&gt;
      &lt;/a&gt;is the most popular Digg clone. It runs on PHP and MySQL.&lt;br /&gt;&lt;br /&gt;
    &#160;&lt;/li&gt;
    &lt;li&gt;
      &lt;a href="http://wordpress.org/"&gt;
        &lt;strong&gt;WordPress&lt;/strong&gt;
      &lt;/a&gt;is one of the world's most popular blog publishing platforms and some of the most trafficked blogs on the internet run on it.&lt;/li&gt;
  &lt;/ul&gt;
