I will wait for version 6, as that has many much wanted functions listed. Those functions, will transform vbsocial from a nice notification system to vital functionality.
Especially the moderator notifications are critical to active boards. Currently vbulletin and various addons do not provide notifications for moderated content. Which means that moderated content can go undiscovered for a long time, killing off activity. For example: I often have 100+ moderated items in LDM, because staff forgets it for a month. You can imagine how annoying this is for members. Similar happens with blogs, images or vaultwiki articles that need to be approved before they become visible.
