What do you mean my "clone sites"? Do you mean all the sites running Q2A? Why is that a problem?

Answer 1

Do you think no one should develop mediawiki, dokuwiki, phpbb, phorum, bbpress, wordpress, drupal, joomla, etc? According to you all the forum sites created by using phpbb are clones. All wikis built using dokuwiki are clones, and so on. If you are right, no one should develop any opensource script, and no one should create a site using opensource scripts!
