This topic kind of rubs me the wrong way...but i'll give it a shot to voice out my opinion. I am still fairly new to utau (only used it for about 7 months--not counting all the months I was deprived from a computer) so don't take me too seriously. I know I might get bricked.
I, generally, don't mind self-advertising. I mean, yeah, if you're new, you've gotta get your hard work and effort to center-stage. But, that's only fine to a certain extent.... I mean, I got really self conscious when I felt that...i may have been over posting or overexposing when I was new(still am a bit). It's gotta be done....it's just one of those things. But the self advertising was not for the attention and "oh wow what a sugoi voice, ne?" comments but the feedback (for lack of a better term) and just pure appreciation of my hard work that kept me going. I'm sure a few, if not all, people can agree that when your effort is appreciated, you just feel so good inside and just want to keep going with it. It's like you didn't waste your time and want to keep progressing and growing.
But it becomes bad when all you ever do is ADVERTISE. I mean, people don't notice it, but they ADVERTISE in ways that they don't even realize, like socially- This is REALLY big. If you have a bunch of friends around the community and even more so if they are popular, there's a high chance you will become popular. This isn't necessarily direct advertising but...it's like you spam your friends or the chat here just to get more publicity. This, I hate THE MOST. Having a bunch of friends is really nice. Really. But until you start to notice that your subscribers and views are all just from friends...it's just, to me, really...disappointing. What if you had no friends? Where do you think your utau'd be?
I mean, it takes a lot for an utau to become big. One of the main factors are time and quality. If you've been an utau user since UTAU was first released then yeah--you'd be a household name. Heck, you might be on top quality-wise as well. But if you're just getting the hang of it...and you're just beginning to see the tricks and are barely skimming 20 subs, then it'll be hard. Self advertising is what gets you up on your feet for a while. Once you begin to run, forget mostly about it and rely on time and the length of your footsteps to get you further. That's my view on advertising.
