Okay, here are some answers to frequently asked questions about my YouTube channel Numberphile2.
1. What is Numberphile2?
It is the second or supplementary channel to Numberphile.
2. What is it for?
It is designed to host Numberphile material that I do not want to put on "main channel" for various reasons.
3. What sort of material is that?
It could be anything. Mainly it is "extra material" cut from Numberphile videos. It could also just be stuff that I thought did not quite belong on the main channel or behind-the-scenes stuff. Maybe it is too niche, too long, too short, etc.
4. But I love seeing all that stuff, why not just put that on Numberphile?
Because Numberphile has a large following (about one million subscribers) and casual viewers do not want their feeds clogged up with "extra material" or 2-3 videos every time I put something new out. They just want the headline act.
Numberphile2 can be a channel for the real die-hards who want everything. Like a little club for the true believers! :)
5. Why not just put that "extra stuff" on Numberphile (main) and make it unlisted?
I used to do that, but the material then becomes impossible to find in searches. And some people do want to be able to have this turn up in a subscription feed in some form so they don't miss it.
6. Then why is some material on Numberphile2 still marked as unlisted?
There are a few reasons that Numberphile2 videos START as unlisted and become listed later.... The main one is this: When I release a new video on Numberphile, I probably release the "extra material" at the same time and link to it from the main video. If I made them both listed, they would turn up in subscription feeds around the same time, increasing the chances that people might watch them in the wrong order. To get around this, I make the second video unlisted so it does not show in sub feeds... I then list it a few day later.
7. Why is the logo/avatar for Numberphile2 the number 2 and not Tau?
The current avatar for Numberphile is Pi on a brown paper background - a famous "number" everyone recognises and it just looks cool. Now because Tau is 2Pi, many people think that should be the logo for Numberphile2. I agree that people who "get the joke" would appreciate that. But I think it would be confusing for people who do not. For a start, Pi has two "legs" and Tau has one. Some people might think Pi should be the second channel logo? The number two is just really clear and obvious... It says: "This the second channel". Sometimes it is best to not be too clever.
Should I subscribe to Numberphile2?
In some ways, my advice to casual viewers is "no". I will usually link to Numberphile2 material from main videos, either via links or annotations.
I will also let people know about anything great on Numberphile2 via Facebook and Twitter.
However if you are really into all the extra stuff and not want to miss anything, than of course please do subscribe. I appreciate all the support!
