It's December, which means snow on your blog, if not on your street
Winter's officially here, in the Northern hemisphere at least, but snow is a little elusive in most places. With global warming becoming more and more "popular," chances are it's going to stay that way for a while.There's not much to do about it, except stop using your car so much, lower your carbon footprint and wait for a few (tens) of years for things to get back to normal.
While you can't do anything about the snow outside, you can add a bit more snow, for a more "Christmasy" feeling, to your blog.
If you host your blog on WordPress.com, you'll know this is an old tradition. It easy to get snowed in, just go to Settings > General, in your Dashboard, and find the setting titled "Show falling snow on this blog." That's it.
