I think this is without question analogous to Stripe. As pg said, the reason Stripe was able to succeed is that no one else was willing to do it: it was too obviously hard. The mountain that would need to be climbed was apparent from the start.

I think this one is similar. Aggregating all of these events for all of these niches from all of these websites is just both so obviously needed and so obviously difficult that no one has wo/man'd up to do it (at least as far as we know).

I have lamented on this one since at least 2007 when Yahoo bought that startup that was trying to do exactly this (can't remember the name).

One day it will happen and the world will be quite a bit better. Obviously :)
