OK, I for one have no idea what the recent blog post is talking about. Could someone please summarize what it was about?
It's commenting on improving yourself in a skill that you really are striving to get better at. The "skill gap" is acknowledging how far you are from where you want to be. It could be comparing yourself to a master like Leonardo DaVinci, or it could be against your roommate who draws cool stuff all the time, or some person online. By studying you acknowledge where you need to improve, and by practicing you can close that gap.
It's annoying because the more new things you discover and want to be able to accomplish, the more and more you need to practice to do that. When you think of new ideas, your goals get further away from where you are, in a sense. This isn't a bad thing, but it can be frustrating. Some people see that there's SO MUCH out there, and think there's no possible way they can ever be that good. Some see how much there is and get so excited they can't help but shoot for it!
On the other extreme, if you ever stop broadening your goals, you may eventually do everything you want to do... but then you will stop growing. Any skill that doesn't grow will slowly get weaker and die.
I probably took it further than the devs really meant to there, but there ya go.
Great quote. Instead of taste, I always think of it as my "vision." I can see the coolest art in my head, but I can't quite get there. Once I do get there, it's gonna be kickass, and I truly believe that. THAT is what makes me want to take on projects like the KS fighting game.
