Grad Skool Rulz
I've just discovered a great blog: orgtheory.net. The whole "academia" category makes for interesting reading. But graduate students will particularly like the "Grad Skool Rulz" by Fabio Rojas. There are 13 so far, with such topics as "writing your [bleep] dissertation " (he used characters in the title that won't allow me to hyperlink; hence the "bleep") and "learn the unspoken rules," these "Rulz" offer insights that you don't usually read in the official university manuals. So far the Rulz haven't been given their own category, so your best bet to locate them all is to go to the blog and search "Grad Skool Rulz #." This will give you just the Rulz posts and not mentions of them.
