Experience is the best teacher though. I can confidently say after trying nearly a dozen scripts, including Elgg, Drupal, SocialGo, KickApps, Handshakes, PHPFox, and JomSocial. Dolphin comes out as the sore loser in terms of user friendliness. In fact, the only advantage Dolphin had over them is being FREE and that is the marketing ploy I fell for regrettably.
