[What] should we do next, following the pattern of our successful "Hagada - Mi Yodeya" project this past Passover?
About half a year ago, Mi Yodeya put out its first publication for printing, "Hagada - Mi Yodeya". In the three weeks preceding Passover, we managed to pull together a 46-page PDF of edited Mi Yodeya content that was downloaded thousands of times and used to enhance many seders, spreading some of our best Passover content in a new medium and new markets.
Now that we've done this once, we have experience, a publication template, and a production process that we can build on to make more publications in a similar way. If we do so with more than three weeks from proposal to release, we can make them even higher-quality and better-promoted than our first effort.
So, shall we have another go or two at it? If so, what project[s] should we pursue next?
Hagada - Mi Yodeya version 2
This would be a revised and expanded version of our first hagada companion. I don't think we've generated enough new Passover content in the past year to make something with all new content, but we can add new stuff that deserves to be added, possibly subtract stuff that isn't as fitting or high-quality, increase the quality control, possibly add helpful features like a bibliography, a glossary, or a question index, and promote the publication more deliberately and extensively.
Chanuka - Mi Yodeya
It's actually already getting a little too late to have a Chanuka publication not be another rushed effort, but I'm including this as an explicit option in case someone feels strongly about it. It is, after all, a very popular holiday. Topics could include various Chanuka practices (Halacha or Minhag), Chanuka lore, and Chanuka Torah readings about the Nesiyim and the Menora.
Purim - Mi Yodeya
Topics could include various Purim practices (Halacha or Minhag), Megilat Esther, Purim's Torah reading about Amalek, and Purim Torah.
Shavuot - Mi Yodeya
Topics could include various Shavuot practices (Halacha or Minhag), general Yom Tov practices, Torah study (how to and philosophy of), the Sinai Assembly and Decalogue, other topics in the Torah/Haftara readings. A special emphasis could be placed on Q&A that leads to or facilitates deeper study.
(a - c) Hagada v. 2 and also one of the other projects listed above
There's enough time between now and Spring that we might be able to pull off both a revision project and a new project, and whichever comes out first could help promote the other.

Please post at most one answer per distinct project or project combination that you'd like to support. (In other words, this question shouldn't end up with more than seven answers plus one for each distinct "Other" idea someone posts.) If the option you'd like to support already has an answer, please vote it up and edit in any additional supporting arguments you'd like to add.
