The downside - and I'm in favour of wikis like Wikipedia - is that any yahoo or otherwise can also put misinformation in there, perhaps even in good faith, and that's in the wiki forever too.

And those who comb through article histories will have to contend with both the truth (we hope, whether we like it or not) as well as the nonsense.

One other difficulty is Internet-based sources disappearing or re-formatting, breaking links from Wikipedia and other places. This is the reader's reminder to donate to the Internet Archive if not Wikipedia itself, providing you can spare a little money to throw their way.

Speaking of the archive: Anyone know whether Russia blocks the archive or maintains their own equivalent?
