With all due respect, I am not against change itself, but I am against it when things don't change for the better. Honestly, the DriveThruRPG.com BAREly loaded before timing out the first time and it refused to load Malhavoc's product offering page. I tried to load it 20 minutes later and the front page simply didn't load for me.
For me, RPGNow.com is fast and easy to use. I think all the people that refuse to do Paypal.com are simply silly... Right now, Drive Thru RPG isn't fast or easy to use, I can't even navigate the webpage more than two clicks without running into a timeout error.
I think it's a big business mistake for you (Malhavoc) because Drive Thru RPG doesn't have a proven track record, nor do their webmasters have a proven track record. No offense to Sword & Sorcery Studios (or White Wolf), but I don't think you can point to their website as user-friendly. Unless Drive Thru RPG seeks outside help from someone more capable, I think it will experience some growing pains for three months if not longer. There's only so much people are willing to put up with before they decide it's not worth their effort.
edit: I concede that there is the possibility that publishers under White Wolf do not have much choice in the matter.
