I only got 165 hits for "drupal sucks", and the first two were my posts on drupal.org explaining why it doesn't suck. :-) I should take that phrase out of my .sig on drupal.org -- with drupal's good SEO results, I could drive the number of hits for that term up singlehandedly. :-) It's also a matter of what you're looking for. "Drupal is powerful" - 207 hits "Mambo is powerful" - 75 hits "PostNuke is powerful" - 16 hits "Plone is powerful" - 362 hits "Drupal is flexible" - 246 hits "Mambo is flexible" - 32 hits "PostNuke is flexible" - 0 hits "Plone is flexible" - 3 hits There's always a danger in putting too much weight on google results like that -- even using it to measure 'buzz' is touchy due to the way search engines work. That said, if people are saying that Drupal sucks, it might be good to ask why. I notice that a lot of the 'Drupal Sucks' flames (the ones that were actually about Drupal) revolved around the limitations of the forum system. That point certainly is a good one. --Jeff
