Events I'm looking for span a range of interests, artists, bands, topics, hobbies, and causes - hence no one central location has a list of everything relevant to me. So I'm forced to regularly dig through Meetup, Eventbrite, Facebook, Google Events Search, individual sites, individual web pages, AXS, Spotify Concerts, email newsletters, etc.
Building another event organization platform isn't the solution - getting people, venues, and organizers onto it would be an expensive uphill battle, and would further fracture discovery. But a thought of a decentralized open-source aggregation of a bunch of feeds has been popping up in my mind lately. These could be sourced from all of the above mentioned sources and somewhat standardized into a format with name, description, price, location, time. From there, it should be a simple matter to add filtering, subscriptions, and even a recommendations engine.
Has anything like this been attempted? Might it work? I haven't found anything yet.
