Is this worth revising?
I am very glad that Don has done the work he has done and I hope he'll continue as long as he can. But the question of "is it worth it" is going to be different for different people.
Don's been studying Epicurus a long time and he's free of the orthodox peer-pressure. But to even recognize that pressure takes a lot of reading, and a lot of the process involves UN-Learning what is written on Wikipedia.
So for a lot of people I wouldn't recommend spending a lot of time there.
And that doesn't touch on the dynamics of wading into a battle of dealing with people who are committed to opposing viewpoints, and the very nature of Wikipedia and the way it is set up.
So as I see it for those who have time to work on an accurate presentation of Epicurus, I'd say that time is far better spent setting up your own blog or article or book or website or video and starting from scratch to explain Epicurus more correctly.
Even worse than wikipedia are many of the popular videos on Epicurus. If someone has talent in that department, probably new video introductions to Epicurus would be even more useful in the near term than trying to tackle the wikipedia editors.
