If you do it to improve code readability, this is a good idea.
If you do it to type less, you probably do it wrong.
In your example, your methods don't improve readability; I would even assert that they add complexity and decrease readability:
Write? Is it writing something to a file? A log? Right, you should read how the method is implemented (since you don't even have XML comments) in order to know what is the purpose of the method.
Stagger means? Unless this term is used a lot in the application domain, I would avoid it:
Console.ReadLine is much more explicit.
They might help you to type less, if you're writing your apps in Notepad. If you use Visual Studio, Intellisense will make those methods irrelevant. Not counting the fact that if you count using the official C# style, you would be writing
Program.Write instead of just
Write, which means that the number of keys pressed while using Intellisense will be exactly the same.
