My start up business will be a social service that also hooks to a mobile application. I want my users to be able to interact with my service over their phones or on their PCs. Naturally I'm thinking the service will be a huge hit with 1000s of users at a time at some point.
I'm very familiar with Joomla but I'm not a programmer. I was thinking of building out most of the site in Joomla and then having the core elements of my service developed to work within Joomla.
Does a CMS built on a LAMP stack have any limitation on what kind of features/services can be integrated (or well integrated) and can they scale well if the service does become popular?
