I get your point, i agree, and definitely think this post Is well written!
but I'd rather people didn't view them as numbers anyways. Views are people, subscribers are people, and you can't predict em!
it's great if you can not get down over sub losses, but it's not just a number drop.
here's how I like to think of it:
we can't blame people for being wishy washy sub and unsub etc., think of all the channels you watched on TV for about 2 minutes and thought "bah rubbish" and changed it over. Did you ever think of how that might affect the feelings of the video creator? Nope. BUUUT you also didn't intend to offend anyone either, it simply didn't interest you and you moved on.
subscribers are real people (when they're not bots haha) and they move on and their tastes can change. We need to stop thinking immediately that we've done something wrong when people do leave our channels, it'll happen. But also it's not bad to be happy when new folks come along! Doesn't matter how long they stay for it's nice to have new faces to entertain/inform.
personally I don't see any problem with being excited with goals, just think of them as temporary viewers for now, they'll stay as long as they feel, and if they leave that's ok, they've already given us some of their time and views and that's great.
Ps, what's wrong with analytics, it's like the coolest gadget ever. You can see where people come from, how long they watch, age ranges, gender, everything! I just think that's amazing! I don't feel ashamed to check up on them a lot to see them go up and down and round and round. I'm grateful YouTube give us these indepth insights!
