Ask HN: my idea for a side project: social events reminders.

Hi All,

Yesterday I got an idea for a side project and I would like to ask your opinion about that. The plan would be to develop a website to share worldwide "non-private event reminders". For example: Nov 21st at 2pm China F1 GP, Jun 23rd at 9pm Metallica concert in NYC etc.

As a user you can use the service in three ways: - post a new reminder (event) that will be published - subscribe to a reminder and receive a notification by email few mins/hours/days before the event - simply look at the published reminders in homepage

I am calling them "reminders" and not "events" because the idea is to keep them very short and simple. They should be just a reminder of events that users can subscribe to and not full event descriptions with pictures, links etc.

Further iterations will add features such as filters (by category, by regions, by city, by time etc.), user registration, multiple notifications etc.

Does it make sense? Are there any similar services?

Thanks!
