i already have my Twitch account linked and the option to show it on the stream page seems to be turned on.

This happened to me before and I think that you can’t see your own stream on the stream page.

You should be able to see your own stream on the stream page. And I always find myself there.

Don't want to be that person but no one really looks at these. People rather use the speedrun tag on twitch to discover speedrun streams.

It might be true that not many use that. But I use it regularly as it is useful to find new runners of the many obscure games I follow. I can't think of a way to find speedrunners across many games as quickly as with just 2 button presses I need on the SRC streams tab.
