Getting a dedicated server is a very big step and it's the reason why most tech sites stay small. Dedicated servers cost way more than normal web hosting.
Cost can run into thousands of dollars each month.
Most tech sites simply can not afford this. Before making a move to a dedicated server, make sure the money your site generates can pay for the server. The last thing you need is an alligator eating a hole in your wallet every month. It also pays to shop around and don't let the prices posted on the host's website be the final price. You can always work out a better deal, if not on price, then for more traffic or a more powerful server for the same price.
