I've been writing content for a site I'm planning to launch soon in a very competitive niche. I have a .net domain ready that's aged about a month. However, I'm starting to think that my hard work will pay off more in the long term if I go with a .com instead. The short term results might not be as good because the domain will be brand new when my site launches, but I'm more concerned with the long term since this is going to be a big site with many pages that I continuously add to. Is .com really significantly better than .net?
