If there's a thing that Mastodon NEEDs fixing to be more "average user" friendly is the fact that if you click on a tag posted by someone from another instance, you are redirected to said instance.

This is going to be very confusing for the average non tech savvy user.
"Why can't I follow this person? Why am I not logged in?"

I'm no programmer, so I may be completely wrong, but I believe this shouldn't be hard to fix

What makes it even more confusing is that this doesn't happen on every situation, only in certain circumstances, making it even harder for the average person to figure out whats going on.
May not seem like that big of a deal for people used to the Fediverse, but its the kind of thing that will make people giving it a try find it "too hard to use" or "too confusing", turning them away back to traditional social media platforms
