There are lots of sites powered by Drupal. But how to find them?
One way is though google. Searching for
inurl:"user/login" finds about 3,730,000 results, most of them are probably Drupal. Which of them are in English? Searching for
inurl:"user/login" AND intitle:"User account" returns 1,030,000 results, which means more then a million are in English.
TrendsPro reports about 555487 sites using Drupal, 109990 (19.8%!!) of them are in the list of most influencal sites on the web. In comparison, this list contains 8417245 sites using wordpress, but only 1120592 (13%) of them are in the list of most influencal sites in the web. So if you build a site with Drupal, you have a better chance to be on the TrandsPro top sites list then if you use wordpress.
TrendsPro provides lots of other intresting statistics, essential for any IT decision maker, so I highly recommend registring to their free account.
