Well, you're not here for the Birthday Calander or to look for people you just met in a bar. You will not visit a Hive front to check local farmers' market offers or when to expect. You're not coming back to check on school anniversaries or ancient study groups from back in the day. There's no Blackboard here and the timeline is changing very slowly. You can't dwell over massive personal picture archives of friends and family, check the single status of somebody, or place a rating for a business.

Feel free to go and create such features for a Hive Frontend, it is possible but there's no incentive to do so.
