I have just migrated my website from WordPress to Drupal, so if you run across any bugs I apologize while I get the kinks figured out. I discovered the hard way Disqus comments do not migrate well, even if its just across platforms and no URL changes.
Drupal Commerce is an amazing open source ecommerce solution; with its foundation in Drupal it can easily contend with the big cookie-cutter ecommerce solution companies. Except for one area - reporting. Drupal Commerce and reporting seem to have missed each other while its growth skyrocketed. I mean, there are ways to build reports and show your store's revenue...just nothing "perfect," in my mind.
