Here’s a rant.
I love Wikipedia and I hate Wikipedia. It offers the potential to store near-infinite amounts of information and is one of my go-to sources for quickly learning about new stuff.
But dude, Wikipedians suck and are the reason Wikipedia is slowly dying. People are hesitant to create new articles because there is always some rabid deletionist standing in the shadows waiting to get rid of it. Oftentimes the information is completely valid, it’s not spam, it’s not completely unnotable, but once something reaches the “deletion” process, it’s pretty much a given that it will be gotten rid of.
People who are bored/looking for something to do/trying to convince themselves they have control/authority/power over others flock to the deletion discussions and often overwhelmingly vote to delete stuff.
Yet, they are never able to answer the simple question: What harm is there in keeping it? They can’t answer it, because they usually do not have an answer – they do the whole deletion thing not for the sake of improving Wikipedia, but to makes themselves feel like they have control.
TLDR: Fewer people are contributing to Wikipedia because Wikipedians scare them away. No one is going to spend their time adding to it when someone is always lurking there to delete their work.
