How to look busy at work while other people walk by when what you are really doing is secretly reading WoW blogs:
Copy and paste the blog into a notepad document, make it small, and read it next to the Powerpoint Presentation you are supposed to be creating. (psst if you were wondering, this is usually how I write my blog posts)
Send the blogs to yourself in an email that includes a very large picture of your company's logo.
Copy and paste the text of the blog in question into that word document you are supposed to be editing, and fiddle around with the font of it while you read it.
Whilst reading from the little notepad C&P of your favorite blog, highlight and unhighlight random pieces of text from whatever document you're supposed to be working on, so that it looks like you are moving around and adjusting text.
Randomly resize images in a powerpoint file.
As proof that I actually do all of the above things, I provide for you a screenshot.
