Thx. That's true. Will do. Do you think that this is important for the minimum viable product? We're just trying to get it out ASAP and we've been pretty sloppy with the text this time. Sorry for that.
Yes, I think it adds (or detracts, in the case of poor copy) from the credibility of the product as a whole. I actually have a use for the product right now, and I must admit the copy errors when I went through the site made me wonder what other errors would come up.
It's a good idea - don't let crappy copy lose you signups.
