We start this thread with HTML5 and mobile web and application development. First of all because new mobile platforms are popping up nearly daily and the traffic from mobile platforms is increasing. In addition, it may be a good practice to make your site mobile enabled for at least hybrid platforms using HTML5 and CSS3. That will also imply that you foccuse more on minimalism and compact coding. As an example, the well known and respected jQuery library has a competitor, http://zeptojs.com/ that is well suited for mobile platforms where every Kb counts. So it is better to think and care about this before you start on a standard web site if you also intend to target the ever increasing mobile market. The top of laziness is to do everything correct from the beginning.
