What are some little things that get to you?
For me, an example around here is Lurker's profile. It says </delurk>. It should say </Lurk> or <Delurk>, either would work.
An example in the work place is when you are spoiled with juices and breakfast for a week or two straight, then the company skips bringing them in for a day. Its amazing that they bring in food, but then when they don't you aren't prepared!
