Plans for this blog in 2010?

I have been thinking about what I might do with this blog next year because I want to do something that would be (for me) a bit different. I have been wanting to redesign for a while and here's an idea that I am considering.

Firstly, I'd quite like to strip the style sheet down to a more slimline version of what I have now. Over the years, I have added more to the style sheet without removing or redefining the style sheet 'fluff' as much as I could have. As a result, I feel that it is becoming a bit bloated with style rules that are no longer used… or that are not used as optimally as they might be.

Secondly, I would like to try out new styles so my plan would be to create a new style for the blog every month. The basic HTML would remain the same or similar with each iteration but the style sheet would change 12 times over the year. I am not sure I can keep this up for the whole year, or even how different the styles will be, but it sounds like an interesting thing to do and it might encourage me to experiment a bit more.

My initial idea would be to start with a base style sheet and modify this throughout the year. Perhaps Andy Clarke's universal IE6 style sheet would be a starting point? It was designed for a different purpose but has a core set of typographical styles that could be a good 'baseline'.

I will not be going so far as to create a new style for every blog post but I figure that once a month might be possible. Anyway, before I decide whether to do this, let me know if you have any thoughts or comments. All ideas or feedback considered.
