I have way too much free time on my hands

So I've been thinking about a blog redesign. I'm not just talking template, but name, feel, theme, niche, everything. While I love my darling Jane, my blog has absolutely nothing to do with Jane Austen (although EVERYTHING HAS EVERYTHING TO DO WITH JANE AUSTEN) and I've been contemplating moving towards something a bit edgier. What are your thoughts on drastic blog makeovers? Have you done this? How did it affect your readers and your blogging in general?

I have to keep reminding myself of my extreme Gemini nature and the fact that I might just forget all of this if I get distracted by something shiny, but it is something I sort of want to do.

Thoughts?
