Great question, thanks for asking!

I have several library related blogs in my RSS reader, but for the sake of space and time, I'll only list my top five here. These are the five blogs that I always keep up with every week, regardless of busyness/laziness on my part.

1) Information Wants to Free - I feel privileged when I realize that I've been reading Meredith's blog this 2005. She promoted important discussion back then and still does now. I think reading her blog regularly is what eventually inspired me to move from working in a public library to an academic library. http://meredith.wolfwater.com/wordpress/

2) Attempting Elegance - Jenica Rogers. She's like...a librarian Xena. I just love this woman's attitude. She's got gumption and gut in just the right doses and makes you think differently, something I really crave as a professional. http://rogersurbanek.wordpress.com/

3) In the Library with the Lead Pipe - First of all, I just love the title of this blog. Second, they cite their sources at the end of each post, so librarianish of them, I just love it. Third, their posts are full of thought and great ideas.

4) Info-mational - Char Booth - I love this blog simply from a writers stand point. Char is a great writer and her posts are a joy to read and always full of relevant thought provoking material, especially on edtech, IL and library instruction issues. http://infomational.wordpress.com/about/

5) Librarian by Day - Bobbie L. Newman inspired the Library in the Day Of blogging project. She offers great tips and links, most focusing on transliteracy which is turning into a very important topic for me these days.
