Simple changeups can do wonders.
The holiday seasons can be fun, especially to your readers who frequent your site. Simple site changes to reflect things can give your visitors a sense of need to come back to see what you might do next. Much like how I do background changes and random posts on things that interest me.
Which is also is the base concept of why you should do as many updates as possible, the more updates you do, the more people will want to repeat visit to see whats is going on. More blog posts, more comics, anything that gives visitors the reason for returning.
We all know this, at least in the back of our minds we know this. What’s your reason for not doing it?
