Good question...
We're not going wiki due to liability concerns with content and representation. We will be working on a sort of "encyclopedia" format.
If you would like to join staff as a contributor or author, we do have some openings and will be setting up an application process soon.
That's why I mention more a wiki format and approach; I don't have that kind of time, nor do I suspect do many. But on a passive level of commitment, simply drive-by as errors/omissions are noticed, it's easy to quickly improve the data.
The rare items database, for example - the rares community could likely very quickly get a far more complete listing put together as people notice missing stuff/details. Just to mention 3 people, Manticore has a great list of event items, Angel Dust keeps alchol-related items listed, and I have lists I maintain of rubble types, hues dyes and other things, pies, etc. None of us is going to have the time to build a full database as a giant project - Decadence tries at her site, and it's way too big for one person, or a static listing, to handle - but in a wiki-type format, many hands would make it a much easier and far more valuable reference.
Same for events; Longtooths and I put together ultimaonlineevents.com and the calandar of events there. It's something that'd be far better handled here, though, with EMs directly entering official events, mods entering shard-wide events, and players entering player events. Hopefully something to allow you to filter between player and official events as well. Text lists are all fine and well, but there was a huge need for integrated/accessible schedules of these things, hence the google calender I started putting together, which formed the core of that site. But again, even for the small group that cooperated to try and keep it up to date, it's a lot of work, and mostly that work duplicated the work EMs/etc were doing on a per-shard-basis anyhow. (And it depends on us noticing such events have been posted, wherever they do get posted.)
