Hard not to notice the new color scheme, right? Eagle-eyed viewers will also notice the absence of ads and the addition of labels. In lieu of a fully-functioning search engine (still trying to figure it out), the labels should allow you to easily find posts based on content. I am in the process of revising the labels themselves but give it a whirl and let me know what you think.
edit: Search engine has been installed but results are less than stellar. Although it is great at doing keyword searches and all that sort of thing, it sometimes directs you to a page which is a month's worth of blogposts...pretty irritating. This will be a work in progress, please bear with me.
edit edit: The new search engine courtesy of FreeFind seems to be working well. Let me know if you experience any problems.
