The site is oriented on business users (in cosmetics market) so I imagine profile of visitor — not to techy. My question: is it worth putting all this new stuff into the website? How many *common* people use these features on daily basis? I have a concern of putting entire system into this domain, because I fear that in effect nobody will use these features anyway. I don't mind the users — no problem for them. I do mind site editors and maintainers.
