The opinion of a few people shouldn't matter, it should be the majority that matters.
The problem is that people have the tendency to speak out when they hate something but rarely praise when they like something. 30 people on a forum saying bad stuff about a design doesn't represent the complete customer base of Dynadot.
Dynadot can easily find a more accurate feedback on their design by implementing a 30 day poll where people can vote which design looked better, the old one or the new one (with one random voter getting a price to get more people to join the poll).
This is in my opinion a good way to find out what your customer really feel.
Ok, this site is still ugly. You would think with so many of us complaining about how damn ugly it is, you would have done something to fix it. But no. You apparently either like things that are ugly or you don't give a rat's ass about what your customers think.
Seriously, this design is awful, bad-looking, beastly, deformed, disfigured, foul, frightful, grisly, gross, grotesque, hard-featured, hideous, homely, horrid, ill-favored, loathsome, misshapen, monstrous, not much to look at, plain, repelling, repugnant, repulsive, revolting, unbeautiful, uncomely, uninviting, unlovely, unprepossessing, unseemly, unsightly
You asked what seems objectionable about the DynaDot site.
The site is very blocky and dark. White dropout text on grey lacks contrast. To the western eye the visual message implies a harsh and impersonal enterprise. Consider something like a pirate's flag for example.
The site doesn't render well on some browsers. The fairly rigorous W3C (World Wide Web Consortium that's been promulgating browser standards for quite a while) markup validation service found 26 errors and 2 warnings. That said, there are some sites out there that will render only on HTML5, Flash or on a specific browser so I suppose it could be worse.
All in all, the site gives the impression of a good high school project but hardly that of a competent professional.
On the plus side it has only a few JavaScript weak spots. I tend to run with my debuggers on and it's remarkable how many sites do not have robust JavaScript. Ironically, the wonky scripts are usually for advertising, tracking, and more nefarious purposes.
The sad part is that I too am among the comparatively long time users who are gradually moving away from DynaDot in the face of what I see as a two year long shift away from what had once earned DynaDot a reputation as a constructive, trustworthy, helpful, decent and reliable registrar. Perhaps the new site design is indeed the correct and proper face for the "new" DynaDot.
