I see how that might be a thought, but it's actually the opposite. AppSumo is absolutely awesome for SaaS businesses as it's a customer acquisition technique- get them hooked for 3 months with what amounts to an extended free trial. If they like it, they stay.

For downloadable stuff, like PadPressed, it's not the best thing in the world, especially when we're surrounded by even more awesome people like WooThemes.

I helped do this, just because I want to see everyone get these tools + blog more. Simple, straight forward :).
