I built FaqMe because I wanted a simple content management system to manage all my FAQs for my various projects. Then I decided to go insane with the UI and stats n stuff & make it more awesome than I would have if I were just banging out an FAQ.
Yes, you could code a FAQ yourself, just like you could code a blog yourself without Wordpress. But hopefully this makes it easier for some folks (much like Wordpress makes it easier to blog).
(also it does more than just FAQs -- there's also a 'contact us' thing that routes customer service emails through a FaqMe inbox in a deceptively simple way, and supports replying & threads n stuff. i know this description doesn't make sense. i should make a faq about it;)
Ps- I never know whether to write "a FAQ" or "an FAQ" ('fack' vs 'eff aye cue')
