How often should one redesign one’s website? The cookie-cutter answer is around 24 months, and in my experience, it is about right. My web design clock has been ticking for a while, and I have started to ask myself the usual questions: what kind of impression should the website leave? Shall I use warm or cool colors? A triad of colors? A tetrad of colors? etc. Finally, the key question comes up: serif or sans-serif?
