I have an idea for a social media site ( Facebook clone ) I'd like to try, but I'm running into a couple snags. The first is, I'm told it won't work well on a shared hosting account once more than 20 people sign up. Something about the data having to be open and running for every person who is loved on bogging down the speed of the site. That's perhaps the biggest hurdle I have right now, as I don't have a shitload of money to spend on it ( although I'd like to monetize it enough to be self-sustaining within a year ). The second question I have is, does anyone here have any experience with any of the vast amounts of programs available out there? I've looked at "The Social Script" , Elgg ( which makes my brain hurt ) and this one among others. I know I could easily fire up another forum for the idea I have, but I'd like it to be something different.
