User blog comment:Brandon Rhea/New Page and Article Headers: Official Release Date/@comment-31403332-20170614064322/@comment-23865-20170614103344

A big part of what the header should DO for your wiki is provide great navigation to your readers.

A sad fact about the old nav (that you may not know) is that only about 1.5-2% of your readers ever used it. People predominantly find their way around the wiki using in-content links that you create using wikitext.

That's exactly what we want for most of the exploration-type moves that wikis are so good at providing. You know, I go to Luke Skywalker, from there to Vader, jump to Galactic Empire, and then to Battle of Yavin. All good. :) Point-to-point navigation, lets say.

What in content links are not too good at is taking you to a grouping. So I'm at Luke Skywalker and want to read about other Jedi. That's why we have categories, right?

So far, so obvious. Now, the thing is the categories are buried deep at the end of the page, which makes them hard to get to for a user who just wants to get from A to B and doesn't know our site very well yet.

That's why we're looking to see if placing the categories at the top helps these people. We're going to be checkin if these links are clicked a lot or not. And that's why we've put them on top while also keeping them at the bottom. :)
