So I'm not as concerned about connecting to those, they're great features to have. I'm more pointing out some flaws from a conversion perspective. Just having those features doesn't do much unless I understand how they work in the context of your entire tool and maybe I'm lazy but I don't want to have to actually use your site as a project tool to figure out if its worth the considerable friction of switching project management tools.
The site is really lacking some form of a walkthrough or demo site or something that demonstrates that your product will do what my current tool does, and how its better. This isn't a blue ocean strategy, its a very crowded market with some very entrenched incumbents, just saying "It integrates with Google Docs and Dropbox" isn't really cutting it.
