The events are of any interest category (as varied as the interests of the users posting them) accessible with or without an account; logged in or not. Once a logged in, you get a special group calendar network with unlimited calendar platforms (called planns) that organize your activities.
The problem is that there is not a central database of all public events all over the world. The point of a public event is that anyone anywhere should be able to find it; does a T.V. or newspaper ad get everyone? Do they even get your target audience? The lack thereof is a direct cause of missed opportunities both for; people local to an area not being aware of things happening outside their circle of influence [family, friends, acquaintances], and people new or visiting an area (business, leisure, or new settlement) not being aware of things happening in their current/new location.
Plann is the simple but big solution. Plann leverages the power of crowd-sourcing to create a central repository where anyone can find any public event happening anywhere in the world; anytime!
Think of it as a craigslist for events [business or leisure; workshop conference or party] built on the principles that were used to establish mint.
Plann provides a special calendar interface where anyone [from a large scale event organizer like the Olympics to a person just giving it try] can post a public event for the whole world to see in the appropriate category so it’ll reach the target audience – all for free. A person browsing through events can filter results by date, category and location on an interactive inset map.
List all major “players” in the system (eg. a marketplace may have two major players: buyers & sellers)
List out any selfish reasons why each player would need their contacts/friends to join the service
List out all things you could possibly charge each player for on the service
For 2 and 3 above give a very short reason you think the player would be motivated to need their contact or pay for the service
