Thank you for a good obituary for the Encyclopaedia Britannica. When it goes, its passing will be the end of an era -- and not just a passing of technology, a passing of quality.
While Wikipedia is an amazing effort, it will not ever be Britannica, unless you pour a lot of money into it to hire writers and editors. They are both a luxury in the Internet media world, and the lack of them shows in the uneven writing and many factual errors Wikipedia suffers from.
You can still rightfully call Wikipedia an experiment. There was nobody who could apply that term to Britannica. It strived to be a reference worthy of inclusion in all the libraries of the world. It shaped our world. Be a little bit in awe of it before it finally sinks beneath the waves.
