Blog layouts

So what do you think, should blog layouts change regularly?
well thats a question for lockergnome.net 
A user said:


A good UI is one that has as little design as possible, you want it to be as efficient as possible so you don't have to change it.
If you have a blog and it is not very popular and it only has a small number of regular visitors then a change that they don't like could cause them to leave the site. Even a site as large as digg.com lost a large number of their users when they changed the UI and features of the site.
If possible, if you want to make a change, find a way to have 2 versions of the site and have users vote on which they would like, the old look or the new look. People are very reluctant to change especially if it doesn't improve efficiency, this is why many got angry at even the newer versions of ms word because a part of the redesign was to put less options but bigger buttons on the main screen and bury other commonly used tools in a menu where it took multiple extra steps to get to. 
well what is your opinion?
