The first blog I ever read with any regularity, and that really showed me what a blog was all about, was "Waiter Rant." I've always tried to be a good tipper when eating out, but after reading the Waiter's writings, I made extra sure to do so. The Waiter fulfilled a dream that few bloggers dare hope for, his writing was so popular that he received a book offer. Today his book came out, and he exposed his true identity. I hope his books runs well (looks like it's off to a good start), and that he doesn't come across any disgruntled customers who figured out he was writing about them. :-)
Good luck Waiter!
