Theo Black, web designer and husband of author Holly Black, took to criticizing the websites of his former clients. I think Black is a talented guy but his vision of website design is style over functionality. I much prefer the functional and generic websites that he disdains because these sites are easier to navigate and faster to load.
But whatever your tastes in website designs are, it makes no sense to publicly criticize an author for leaving you. It’s bad for business and tacky.
I think that there are some schools of thought that because these are sites for authors who are artists, then the site should reflect their vision. I think sites are for readers and should cater to their preferences. Teddy Pig wrote an article on site design for epublishers and I think the comments at the Smart Bitches site are also instructive of what readers are looking for.
