Infamously popular? Troll science, is what I smell :P Yeah, people vote down on my save too, apparently little kids lose interest and spam their much-unappreciated votes across good ideas far and wide. Oh well, the world is not perfect, and far from it too. I can't believe half the people who vote for my ideas either hated it or were to much of a simpleton to understand its universal design. Isn't simple better? Less errors means better functionabilty, right? :P
In all honesty/seriousness, for me, linking to any of your other creations is an automatic down rating because I take that as you simply being a "upvote whore". Nobody likes an upvote whore. There are exceptions to the link rule of course, such as a link on a save of a computer linking you to a place to program something for it or things of that nature.
TL;DR: Don't be an upvote whore because that is a good way to get voted down once you make front page.
I never really thought about it, but I think I sorta agree with Joshinator. I also downvote saves with bad grammar and/or spelling. If it isn't A+ material, it shouldn't be frontpage! Conventions are part of every grade!
