[I'll probably pause the Ulysses annotations here for a while, while Frank Delaney catches up. Since new visitors will see this page first, I'll try doing a survey here of the various annotations projects, arbitrarily favoring p82 to see how they handle Throwaway spoilers. (Only the rarest of readers could have caught the reference immediately.)
Groden coincidentally chose the same passage, and enumerates eight possible hypertext formats]

The standard book of annotations by Gifford and Seidman gives away all details of the race and the tip. It includes no images (or songs). They use Gabler's linenumbers, plus a post-1922 edition. GoogleBooks allows linking to most pages.

The earlier standard by Thornton skips the page completely. Groden adds that, in their endnotes, Declan Kiberd offers a greater spoiler than Jeri Johnson.

Slote withholds any spoilers, but introduces a wholly new pagination with tiny Gabler-crossrefs only after each endnote, and some dozen unsightly marginal numbers on each page, for those endnotes.

Wikibooks hasn't reached this page but allows user input, discussion, and links, with the 1922 pagination.

Aida Yared's images include the Ascot racecard. There's an email address for comments.

Samuel Schiminovich/Jon Reeve experiments with several designs but for Throwaway just two letters are highlighted with a popup textballoon when you hover, with a short spoiler. Each chapter gets one webpage, but there are indexpoints every ten lines. Email addresses for feedback can be found by trimming the urls.

Barger included links about the race, with Gabler's linenumbers, one webpage per chapter with indexpoints approximately every 50 lines, with the chapter text in an optional frame. The contact email and discussion page are expired.

Hunt's Joyce Project has started the chapter but not yet reached the page. We can anticipate highlighted text, with a popup that spills the beans freely, probably with pix and links. Linking chapters is tricky, but linking the popups alone is easy. There's a link to a form for feedback, with the promise of a discussion forum.

Amanda Visconti's UlyssesUlysses is stalled at ch2 but shows highlighted phases that show marginal notes when hovered over. One webpage per chapter, no indexpoints. Her successor app will be called Infinite Ulysses. Contacting her is a challenge.

RapGenius allows you to add notes, images, and links in popup annotations, with one page per episode. The interface is fun but the community can be vicious, can't be trusted.
