It took me a long time to get Tumblr, like many others I wondered what it was for, why would I use it instead of a blog? All a bit of a struggle for a computer geek to understand, we have so many tools on the internet such as wikis, blogs and forums that are designed to solve problems and bring us closer to realisable outcomes. We developers share traits with scientists and engineers in that we look at the world in a logical way looking for cold rational answers to questions.
