This 100x over. I've been trying to find a convenient way to block the domain from all my devices. It's all just utterly content-free cyber squatting.
Of the things destroying the internet (Google AMP, and Pinterest, in that order), I wouldn’t include wikihow.
And "it's a wiki" isn't a defense. What is my motivation to improve it? Nobody trusts wikiHow anyways, so contributing would just be creating more content that nobody should trust.
I do overall disagree with the thrust of your comment, though: your anecdote and mine cancel each other out. You haven’t been helped; I have! On balance I think they are helpful. I don’t have access to the statistics anymore but from what I remember, more people interacting with the website rated articles positively than not.
wikihow could be valuable if the content it contained had some generally assumed level of authority that was better than the internet at large, so you could assume that a wikihow article was more trustworthy than any other random result from google. as long as wikihow articles can't be assumed to be more helpful than any other google search result, google is a superior alternative to wikihow.
