I have a site that's doing very well, but I also have another idea I want to start up which is definitely related to the niche of my current site, but approaches it from a different angle. Is it a good idea to build out a second section of my current site and have two separate, but related, services running on one site? Or should I just make a second site with a separate brand? I would like to expand my current brand instead of making a second separate site and business, but offering these two separate services would require a separation. This means the homepage would be transformed into a portal asking the user "do you want to do this (the original site) or do you want to do this (new section)?" My site is making money and people like it so I don't want to fuck with a winner if it's a bad idea. Any feedback here would be appreciated. What do you think?
