Questionify - Q&A-Powered customer support

I hate to spam, but I thought this app could maybe help you/your startup. Questionify is at the early stage and I'm following the lean startup principle, so I'm looking for the initial customers.

How is Questionify different from GetSatisfaction/Tenderapp/Uservoice? Questionify is a Q&A platform that lets your customers ask questions. Your employees answer them through the web interface or by email(you get an email every time someone asks a question) and your support page is updated in a matter of seconds. You can upload screenshots or paste YouTube URLs in answers, we'll convert them and prettify the answers.

Fully brandable. Questionify is full brandable, you can style it by uploading your company's logo, setting the brand colors.

No registration necessary for posting a question. Your customers dont have to register on Questionify to post a question, questions are monitored through the Pending Questions tab.

Subscribe to a question. On every question page, customers can subscribe to a question(by leaving their email) and get notified when that question is answered or if the current answer is changed. Customers can leave their email when creating a question and they're automatically added to the question's subscriber list.

Questions are sorted by category and views. Every question belongs to a category which you can create/edit/update/delete, questions belong to categories. For instance, if Hacker News was using Questionify, some categories would be: issues, submitting a post, jobs, etc. Every time you open up a question it's rank is increased by one(backend: questions have a views field which is auto incremented by 1 upon every question view) so that your home page shows the 10 most viewed questions for each category.

I'd love to hear your thoughts, opionions, questions. I'm always on HN so expect a immediate response.
