Modern Rules of Web Developing

In the last years there is a huge hype around web 2.0 (despite the fact there is not any people on the Earth who thinks the same about the meaning of this) and most of the people thinks it's just about shiny graphics, large fonts & Ajax on the pages. I think it's not important what web 2.0 means (and it's also not important to define this buzzword) - but below this hype, the rules of web developing slowly and silently changed - I think we have to notice, analyze & adapt these changes to work efficiently and to produce quality works.

Modern Rules of Web Developing:

1. Connectivity: Never try to reinvent the wheel. If there is an already running, working solution what can be a part of your product - use that! There is hundreds of APIs out at the web - build the next step, don't begin everything from the scratch.
2. Materialize: If you got the idea, put it online as you can. Don't hesitate, or plan too much - try to keep the quality, use just the necessary features, put it online - the visitors & customers will know and report what kind of features they want so you can prioritize the features later.
3. Usability: Usability is everything. Don't think a simple design or a lot of features means usability - you have to be a user, as we are all users, when you think about that.
