Oh no, definitely not thinking anything as big as facebook, myspace or the like, and very likely no where near millions of concurrent users per second. However we do expect 6 digits easy within a year and a half or so. More so with the companies we are currently in talks with for partnerships. Hence why I am seeking to find out just how extensible CI really is, as we don't really want to build up a service that we will ultimately have to rebuild in favor of something else later. We would rather worry about enhancing instead of reinventing for at least a good while. That said, I know we will be needing multiple servers. My team has built a few social service like sites. Where we have ran into issues with bottlenecking our servers and causing them to crash due to improperly handling the loads (which I know balancing is all the server end and not the script end, however there is the rubber band effect, you pull a file to many times within any given second you can cause it to snap temporarily and result with a 404 like error).
