One of my personal favorite blog reads is AdRants.

Here’s how author Steve Hall describes it.

Reporting on the brilliance and idiocy of the media and advertising
industry, Adrants offers subversive comment on the questionable, the
absurd, the new and the noteworthy. Everything from new campaign
launches to useful facts and figures to odd little items from the fringe are
delivered with wit, humor and sarcasm.

Just go there and prepare to learn and laugh.
