TopDrops.org uses the top 1 million websites list supplied by Amazon's Alexa. It checks each site weekly to see if it runs Drupal and then lists the top Drupal websites ranked by their access statistics.
Highlight your site with DrupalPeople
Any website detected to run Drupal will also be checked for /drupalpeople and if that serves a comma separated list of Drupal UIDs, will highlight the Drupal People that were involved in the website. It will also highlight the site in the top list with a blue icon. Use the Drupal People module if you prefer not to serve /drupalpeople manually.
Once in a while, usually each week, the Drupal user pages for those people are also checked to get a username for the UID. If the user page lists a Drupal Association membership the icon for the top site and for the Drupal Person will be highlighted accordingly.
Since we cannot hit Drupal.org on potentially infrequently accessed and/or changing user profile pages on too regular a basis (this may generate undue load on D.o), if you have just updated your Drupal Association membership and want me to manually check your user profile to update TopDrops.org's awareness of your association membership, just drop me an e-mail (e-mail address below).
Find Your Website Rank
This box searches only the most recent list of top Drupal websites we have listed on TopDrops.org (remember, no www).
For your site's overall international or in-country rank, simply go to Alexa and search for your domain name (or just click here and replace burtronix.co.za with your domain name): http://www.alexa.com/siteinfo/burtronix.co.za.
Per-Country Lists of Top Drupal Websites
TopDrops.org has an ancestor. We still serve a list of top Drupal websites for many countries based on access statistics of people in each country and limited by each country's country code top level domain on our older website. It may be updated in future with newer statistics; You never know when time and budget allows: Top Drupal Websites per Country.
TopDrops.org is a labour of love / casual project by Riaan Burger... so don't take it too seriously ;-) Comments, discussion and suggestions are always welcome.
