I am interested about the Worldbuilding blog and would like to read some of the stuff in it but I cannot find it. The blog link at the bottom of the page takes me to stack overflow blog not Universe Factory. I am using a mobile device if that makes a difference. I seem to remember finding the blog on a desktop computer once but would like to find it on mobile.
As Monica brought up in Can we have an SE blog for this site?, Stack Exchange is no longer doing many official per-site blogs, for various reasons. Therefore, our blog, Universe Factory is officially un-official and technically unaffiliated with Stack Exchange in any way, shape, or form, except for the fact that everyone who writes for it is a member of the Worldbuilding Stack Exchange community.
This means that there isn't a link to it on the Stack Exchange™ MultiCollider SuperDropdown™, as there is for the official blog(s). Therefore, you can either bookmark the link on your computer, or find it somewhere on the site, such as in this answer. A better bet is in the blog tag wiki excerpt. Also, there's a link to it on one community promotion ad that sometimes shows up on the sidebar; that might have been what you originally clicked on.
Fun fact: We previously had a Wordpress Blog, Magrathean Forges, but that folded after one or two entries because of lack of interest; the content was transferred to the Medium blog. Before today, the link in the tag excerpt led to that blog, rather than Universe Factory. I edited the link to correct this.
