User blog comment:Ubersketch/Should blog posts be counted as external sources?/@comment-35392788-20190921131341

I think that should be a possibility. The problem with the current source policy is that it tries to ensure quality through external sources, but it fails at doing that in my opinion.

Ubersketch explained the two issues pretty much, but I'll sum them up :

1) An external source doesn't necessarily ensure quality. Anyone can just create a Google Sites page, put some mishmash on there and then try to make an article from it. Now, whether someone would actually do that is up for debate, which brings me to my second point.

2) Conversely, you have a lot of very mathematically interesting things defined in GWiki blog posts. This includes, PsiCubed's Letter Notation, probably the highest level continuous function out there. But with current policy this can't be on the wiki because there's no external source.

To conclude, the current rule is more arbitrary than it is helpful, and instead I think what is needed is simple quality guidelines. If a blog post respects them, they should be allowed on the mainspace. Conversely, if an external site doesn't respect them, they shouldn't be allowed on the mainspace. Of course, guidelines are only outlines, and the final decisions should be left to moderators.
