Can i use .net to make websites?
Already adding to this topic, .NET would let you build websites, yes. To answer the question whether or not it's better to use .NET or not, the answer is: it depends.
Blogs and forums tend to use technologies like .NET, Ruby on Rails, JSP, and PHP to display data that is dynamic (data that changes all the time). They are normally stored in a database back end. You use technologies like .NET to get data from a database to display. Because .NET is a real programming framework (a framework is set of objects you use to build something, think of it as a warehouse of parts to build an engine; you can build any kind of engine because you have the items you need to build it), you can build some serious websites with it.
However, if you don't need .NET or similar technologies, you can just write the HTML and put the content in it. It's simpler to use; you don't need to learn .NET, only HTML. However, if you need to change something, then you have to change the HTML and corresponding content. The amount of monotony depends on how often you change the content on the screen. The more often, the more you want to lean on learning .NET or similar technologies.
As a matter of fact, HTML is just the way we display stuff on the web. So learning HTML is part of the whole learning curriculum of learning .NET.
