Based on the quality of the people involved I expect it'll be good. Here's how they describe Yay.ie:
It’s a place for us to tell you about events, festivals, theatre and more.
We run competitions, share reviews and previews and have fun with what we do.
We post information that we’ve found or from event organisers, marketing and press departments, PR companies, charities and venues to help spread the word.
We’ll be up front when we’re sharing press releases or asked / invited to write about an event. We’ll also share where we found our information online.
