I don't like it when websites change, it makes me nervous and edgy, even ones that I don't really use. For example I use hotmail, when I logout a page comes up with news articles and stuff like that(not certain what else is on it as I don't read it). It's been the same layout for years, today it was different, even though I just close the page and never read the news on there it freaked me out and I thought why? why would they do that, it looks worst!
I am responsible for some website changes as I do web design as a hobby and host/maintain several sites and it annoys me alot having to change things. One person wanted the whole layout and colours changed. I didn't email them back for about a week because I had to get use to the idea but then I had lots of ideas for what could be done and I went with it and changed it all.
