Should I stream Um Jammer Lammy on Twitch?

0/100 · Closed off· 2 viewers per streamer on paper

Probably not. The only English stream here holds all 2 English viewers — once you take it out there is nothing left to reach.

The only English stream here holds all 2 English viewers. There is nothing left over for a second.

Almost nobody here is available to you — either a couple of streams hold the room, or nobody is watching in English, or the category is empty, or you would be buried.

This reads the room as it is right now — how much of the English-speaking audience is reachable and where you would land — not how many followers you would gain. That depends on you.

Where to buy

All plain links straight to the official stores. Some will become affiliate links later, and they’ll be marked with a ♥ when they are — you’ll always be able to tell, and the unmarked ones will always be there.

Is Um Jammer Lammy too saturated on Twitch?
