I have been producing the #BritList for about two years where I look for Brits on Hive and generate a post that indicates how many are active. I have offered to do this for other countries, but have not had much interest to far. I use a mix of @Hivesql and Beem with Python to find people and produce the post.
I ran some searches on other countries a while back to see how active they were. I am not sure I looked at Ireland then, but here is a list I generated today. Not a huge number, but in proportion to the population it may not be much different to the UK list. I searched for 'Ireland' in the profile plus a few major towns. I welcome suggestions of what else I could look for.
On the Brits list I include ex-pats. I am sure plenty of Irish people are now living elsewhere, but I will leave it to others to compile that list.

The two with a * are on an old copy of the Hivewatchers blacklist I downloaded. One of them is just posting and never commenting and the other just votes with a small stake. We have plenty of of accounts out there running on automatic.
I remember seeing there used to be some meetups in Dublin. Do they still happen?
I have not heard from
On a related topic there is a potential London meetup next month.
