While it's great that you found some usefulness from this closed question, I have to agree with the close reason. As it stands, this meets the definition of the not a real question close reason:
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
Essentially, the entire question comes down to this:
Netbeans' look (the font) on Ubuntu is ugly. Has anyone run into this?
"Has anyone run into this?" If I think Netbeans is ugly, and I say, "Sure, I've run into this." How does that help the community? Additionally, from the perspective of someone answering a question, "ugly" is way too subjective and depends on interpretation. This is ugly? To whom? Maybe I think it looks awesome, being an Ubuntu user. Maybe my idea of a beautiful app is completely different than the asker's.
For instance, maybe I post an answer about how I used a different desktop manager, such as Cinnamon instead of Unity. When changing from Unity to Cinnamon, the fonts in all your apps change. However, maybe from the asker's perspective, he/she was expecting the beautification to happen in the app itself, not the entire desktop.
But without details and specifics this is not a real, answerable question. It's pure luck that it just happened to help you, and it's not an example of a great question.
This isn't to say that it couldn't be cleaned up. NullUserException made some improvements, and as soon as the pending edit is approved, I'd suggest getting rid of the "Has anyone run into this" part of the question. It's a completely useless distraction and not important at all to describing the problem so that it can be solved.
Now, if the asker wanted to improve it further, he/she could describe exactly what it is that he or she doesn't like about the font and what he/she prefers in a good font. It wouldn't be a perfect question, and probably still wouldn't be on-topic or constructive, but it would help answerers provide a much more specific and tailored answer that gets at the heart of the problem.
Just as an example, if I were to have a problem trying to get the Google App Engine Plugin, designed for Eclipse, to work with Netbeans, and I tried adding it in through some plugin architecture that Netbeans may or may not offer, and I describe what I tried, what happened, what errors I got, and what I expected to happen, that would be a good example of an on-topic question about a software tool. Hope this helps!
