I love Bloomsday! But I must admit I still haven't finished Ulysses. I've heard its best read with a companion book. Once I finish Dubliners I might try tackling it again.
What I love about Joyce in general is the geographical accuracy of his portrayal of Dublin. It's mad that it has hardly changed over the hundred years since Ulysses and Dubliners were written.
A good memory I have from last year's Bloomsday was walking past a crowd of people in period dress holding pints of plain and talking loudly over a guy reading out a chapter of Ulysses on a podium outside Davy Byrne's. It's not just about the literature, Dublin is all about the atmosphere. It's a pity the weather isn't great for it this year.
the quotation marks are missing
I'm pretty sure that's a stylistic choice by the author himself. All the dialogue is mixed in with the stream of consciousness. A delicious mess.
