Ok, I'm going to start up a social network... I'm looking at pouring a fair bit of money into this as the niche I've found I think will work. Just wondering if anybody has any tips for starting up in terms of getting everything sorted and then the initial task of building up members (I'm thinking it's critical to get things off to a good start in terms of member numbers, and hope it snowballs from there!) Came across this site, would like to fork out for this ebook and check it out but I'm not sure if it would be worth it - http://www.startasocialnetwork.com/ - besides I'm looking at paying over $250 for SocialEngine... and I don't usually pay for anything so I'm a little hesitant about this. Anybody got any good tips/advice for me?! Anybody having success with running a niche social networking site?
