I really dislike posts like (sorry AJ, you are just one example) AJ Towns blog post
“Some fun”. What I dislike? Well, the post lacks critical information: Which slashdot post inspired him? What data is he talking about? How did he turn the data into those graphics?
Sorry AJ, your post is just the latest example of this style of post, and I really got frustrated over such posts, this is not meant as a personal attack.
So to make my wish clear: Please, fellow bloggers, don’t assume that your readers are following your favourite web resources as closely as you do (and with the same specific interests). Explicitly say what you are writing about, reference resources needed to understand what you are doing, at least give readers a chance to find out what you did.
In AJs case, it would probably have been enough to reference the /. article or comment which inspired him.
