Thanks for the posts, folks - this is exactly the kind of input I'd hoped to get. It's all useful!
I've only got a short window to post anything here for tonight, so I'll most likely come back and make a more comprehensive response later - hopefully somebody else mght have chimed in by then.
One thing I will reply to here, though - and I hasten to add this won't be by way of a direct response to Lutga - is this:
One thing I'd say though is ask yourself why you're doing the channel. If you're finding it a chore and having to really push yourself to make content there / having to weigh up skimping on quality to save time, then it's probably best not to push it - I'm not sure there'll be much satisfaction that way, and the 'hits' won't just magically start coming in one day. The brutal truth is that most of the YouTubers who get big numbers are either unemployed, or do it as their full time job, so have the time to work on it 24/7.
This sort of speaks to a minor personal frustration I've had with the channel. And I should point out, this obviously isn't what Lutga is saying here, but it kind of fits in the same pigeonhole, so to speak.
It seems almost impossible to put across to some folks - usually people who have no real knowledge or investment in how Youtube works - that channel performance is a real issue. Any time you even mention the word 'revenue', there seems to be somebody ready to accuse you of only doing it for the money. Youtube would have to offer a LOT more for that to ever be the case, I think!
That said, I've always had a clear goal and clear cut agenda with the channel. Monetization's part of that, but not the be all and end all. My concern as far as that goes is that I'd prefer the channel to be earning SOMETHING to make the effort that goes into it worthwhile. That's a pretty common motivation among Youtubers who are trying to build a channel, I'd say.
Really, though, what I want to do for the time being is just concentrate on building up a volume of material so that the channel is worth folks visiting in the first place. And I think, to attract the kind of numbers I'd ideally like to see, I need to have a lot more stuff there for them to peruse. Even though I the number of reviews I've posted is pretty healthy, it's still small fry.
You might have seen in a recent review that I parodied the intro of Classic Game Room, which is a fun channel that's been going for literally decades and has a massive library of content. What I'd really like to do is make HdE Does anime a similarly comprehensive channel in time. I think that, inevitably, as the channel grows in those terms, everything else will fall into place.
