I am the webmaster of a local news website which is online for 6 months now and I considered redesigning it. The website is running on a Wordpress CMS, so all I had to do is to apply a new theme. But instead, I just tweaked fonts, text sizes and color schemes for more reading comfort.
Why tweaking instead of redesigning ? Because I thought that it may be harmful to user-engagement if readers would have to rediscover the site all over again, only 6 months after it's launch (not to mention all the work just to put everything in order again).
Does redesigning a website frequently good or bad ? How long should I wait before redesigning the site (regardless of platform and content types) ?
