I played with Wix with the intention of using it as a tier-1 for a small business. For what it is, it seemed okay. Not for a serious business owner, but maybe a student, or an elderly person that is not very tech-savvy to earn some small, part-time income on the side, where giving the impression of being a complete amateur is not a negative. Maybe selling quilts, or home-baked cookies.
I see Wix as being 90% marketing, and 10% substance. You never see Wix results in the search engines, nor do you see legitimate, established and fully-professional businesses using Wix as their "public face". Maybe this could change, IDK. I will say that even those businesses that use Facebook as their primary online point of contact look extremely half-assed and amateurish, even if by reading between the lines you can tell that the business is fully-professional. By this, I think of one case in particular where a Plumber had photos of jobs he had done involving quite a lot of heavy equipment; expensive tools that the kid next door isn't going to be able to afford. But I thought the whole thing was stupid, using Facebook as your main internet page, as to my perception it feels more "here today, gone tomorrow" than if a company has invested in a full-on professional website.
So, if that's my reaction to Facebook, and assuming my reaction is typical, I assume that the public's reaction to Wix is going to be even worse than that.
