I agree, but I will also say that you can almost always find ways to get more done with more people. For example, it's easy to break up a project into code, css, html, javascript. That's four people right there. You could also have a graphics person drawing icons or cool backgrounds. You could have a database person. At some point you'll need a networking guru, marketer... It's easy to get into the trap of thinking it's all about code, but there are lots of ways to add people. Sometimes, coders don't want to add people, because it's one more person asking them to code something. Coders often don't know how to push back and say, "This is what I'm working on, this is what I need you to do." Every answer to an IT problem is "It Depends." In this case, the question of "Does adding more people make the project go faster or better?" is "It depends." This question can't be answered with a general absolute.
