That seems to be what the comments to my last post led to.
And Alex Schroeder certainly seems to have the technical skills to make it happen. Just check out Old School RPG Planet, if you haven't already.
In my vision the wiki/blog would be:
1. Primarily links to blog posts / or forum posts that clarify a rule or propose a House Rule
2. These are indexed under a contents that mirrors Moldvay's contents (all TSR and clones would hopefully fit under his broad headings). Imagine with me for a moment an abbreviated heading list...
Definitions of Standard D&D Terms
How to Use the Dice (eg d30 dice links)
How to Create a Player Character (eg 4d6 drop lowest, 3d6 in order)
Hit Points and Hit Dice (eg plenty to say here)
Bonuses and Penalties Due to Abilities (eg all my posts about low ability scores)
Character Classes (eg Lands of Ara bard, B/X Blackrazor barbarian and mountebank, Grognardia druid)
Character Alignment (eg this area would be huge!)
Armor Classes (eg Trollsmyth shields shall be splintered, weapon vs AC house rules)
Clerical Spells (eg vancian or not?)
Spellbooks (eg with links to the recent ChicagoWiz and Jeff Rient's posts)
Encumbrance (delta's rules, LotfP)
Wilderness (to add some Cook titles)
Travelling by Air
Specialists and Mercenaries
GIVING EXPERIENCE POINTS
Combat Sequence (eg Alexis' rules)
Monster List (eg Daddy Grognard and Adventure for Every Monster)
Treasure Types (silver economy)
Magic Items (need I say more)
Choose a Scenario (maybe choose a campaign- sand box or other)
Reviews of old and new material
Novels : Appendix N
3. Allow anyone to put in their own link to theirs or another's post (less work for any moderator)
4. Maybe allow a 5 star rating so readers have some hope of sorting the good from the great
5. And every time it alters have it update in peoples blog list if they are following - keeping that "Click me I'm new" blog feeling. Hopefully there will be some way highlighting the new material.
6. Working title for this project: OSR Links to Wisdom
I'm liking it, are you?
