The announcement on the official BarCamp Dublin Blog is here.
To quote what is barcamp?
[Barcamp] is an informal gathering of people from technical and business backgrounds, where information and experiences are exchanged. The event is geared towards sharing knowledge and learning from others and there is a policy of encouraging active participation in all discussions.
So if you’ve never been to one before, and not sure about attending. Just Go. You’ll be glad that you did.
Update: Paul asked me to change the order of links so that the ‘official’ site came first (previously I had his blog listed top). The original links are below.
Paul Walsh has announced the date of Barcamp Dublin on his Blog. It’s Saturday 21st April in the Digital Hub Dublin. Paul is organising the Event , along with EllyBabes and Joe Drumgoole.
Update 2: I’d forgotten to mention Keith Bohanna’s post about the upcoming Barcamps. Anybody else up for organising a Barcamp north of Dublin (in Drogheda, Dundalk or Newry)?

Thanks for the link mate but you would serve your readers better by linking to the original Barcamp Dublin announcement. My post is just a one liner linking to that post. š
Paul,
Done!
