Option One is to leave things as they are.
Option Two is to go to one blog (then, which domain do I keep?) and focus on books on certain days and have other days for random things.
Option Three is to change platforms and go with something that has multiple pages like typepad or wordpress. But those likely cost money.
Again, I come back to - why do I blog? What is the appeal? I think it comes down to connecting with people I may not already know and share something book-ish (or crafty, etc.) with them that enhances their lives, or makes their lives simpler.
