Blogging for kids

There is this small group students I've taught in the last few years (maybe 7 or 8) who come by my room regularly to ask what they should read next. I'm even supplying reading materials for one of their mothers. Presently this exchange is limited to the 150 or so books I have in my classroom. This seems like a great potential use for a blog, particularly as a librarian. I think it will be challenging to keep it simple and not overwhelming. Also, I don't want to lose those personal moments with kids to chat about the books they just read. Lots to think about.
