My name is Dmitri Popov, I am the author of Helpinator.
WordPress is so popular now that even my cat knows how to install and use it.
It has tons of themes and plugins and a very active community.
Well, it's not perfect, but if you create an app - you can get your site up and running in minutes and there are a lot of inexpensive themes to make it look professional.
Online documentation (or WebHelp) for your product is another good idea - it's SEO-friendly, easy to update and access. But authoring online documentation in WordPress editor or a post-oriented desktop client is a kind of tedious work. This is where Helpinator helpinates your problems. It's a specialized help authoring tool, you can capture screenshots, annotate them, create step-by-step guides, write topics in WYSIWYG editor and then publish to WordPress with a single mouse click!
