[Tried to send the following a few days ago, but had a problem with my 

What about adding a "best before" date on Wiki pages and let moderators 
extend such dates (by a simple click).  If the date for a page is not 
updated, there will be a warning on that page telling the reader that 
the content might not be fully valid.

MediaWiki is a good solution because there you can write equations in 
LaTeX, which are generated as Math-ML(?) and/or bitmap images. This 
feature might be in other wiki system too, I don't know.

That's my $0.02
