Wikipedia vs. Brittanica

Quick followup on the wikipedia authority challenge.

Ed Felten did a quick smackdown comparison; the mighty Wikipedia vs Brittanica cage deathmatch.

Very interesting actually. Wikipedia seems to do very well against Brittanica when it goes toe to toe. Would be interested in seeing how far that actually goes though for a representative statistically significant comparison of entries.

Overall verdict: Wikipedia’s advantage is in having more, longer, and more current entries. If it weren’t for the Microsoft-case entry, Wikipedia would have been the winner hands down. Britannica’s advantage is in having lower variance in the quality of its entries.
