The logos here that aren't gimmicky are totally predictable, and very few of them are "weird". If you liked this post, you will love the "Brand New" blog, which does dissections of rebrandings on a weekly basis. It's one of the very best design blogs on the net:
I agree, Brand New is one of the most focused an interesting design blogs around. analytically dissects the change before opining. Also does a great job showing the before and after and doing some research. Really adds value where most blogs are just links with a sentence or two of filler.
www.core77.com - focuses on industrial design. There is a blog, but also a portfolio and jobsite for designers (www.coroflot.com)
www.designobserver.com - is also great. The writers are some of the top practitioner in the world. It is a little NYC biased, and a touch snobby, but a great resource.
www.thedieline.com - is a blog focused entirely on packaging design. Frequently updated with great design examples. One nice thing about this blog is that they feature high end stuff in boutiques and clever designs you could find at a super market.
Far too many to list, much less read. Find one that you think is good, and subscribe to the ones they link to.
Avoid ones that: never criticize; very frequently post lists, free brushes/templates/vectors/tutorials; use the word "inspiration"; never post anything whose design-relatedness is indirect or not immediately clear or without commentary; or are authored by recent graduates.

Brand New has solid writeups on the LSO and London Museum logos, which are the only two companies in this list I think I even recognize.
