I made a website! Now what?

<!--HTML-->When you finish your website (or a web app) and you are ready to show it to the world, it's not the end of your work, it's just the beginning. Users will ask you to add new features, some bugs will be discovered or you will simply have to answer some emails about the website. But before this happens, you need to put is somewhere, so people can see it and start using it. Now, how do you select which of the 1047 different hosting companies will be the best? Or where do you get a cheap domain? How do you know that your website is up and running when you don't look or how do you communicate with people who subscribed to your newsletter? You don't know? Don't worry, during this talk I will give you some examples of tools and services that you can use when launching your website (with an emphasis on cheap/free and reliable tools).
