This is a humble plea from someone who used to be an animator just like you guys, way back in 2004.
A little backstory: I started animating in 2004, and stopped in 2006. 8 years later, I have learned a horrible truth that was never apparent to me as someone inebriated into this community: our presentation sucks. From people outside the community (people who have never seen pivot animations before and have no concept of the time/effort involved), the most common complaint I hear about pivot animations is how rough they look, but more often how small they are, in terms of dimensions. No one wants to squint at an animation that already looks rough. I apologise in advance if this post is something that has been discussed already; I have been out of the loop for 6 years, but from what I can tell, not much has changed!
So, what can we do to improve our presentation? Well, I have three main ideas. Firstly, and the easiest: work in bigger dimensions. Ensure every frame you work in has an aspect ratio of 16:9, and a resolution of at least 720p (i.e. 1280x720). This aspect ratio will be important in the next step. Export your animations at full size EVERY TIME. Everyone hates the pixellated edges, but nowadays, with the increased availability of huge monitors (1920x1080 and above), the default dimensions of 506x415 are ridiculously small. Not only that, but animators are encouraged to srhink their .gifs by 2, or even 3. A 169x138 .gif sitting in a 2560x1600 (mac) monitor is laughable. Your viewers will have to squint to find it. So, 1280x720 should be considered a minimum.
Secondly, everyone should make a youtube account and post their stuff on there. Subscribe to each other and make the Pivot "scene" more popular. More people will be attracted to the site, which will mean a bigger talent pool, which means a higher overall standard of animation. Remember the bit about making animations have 16:9 aspect ratios? This makes it perfect for uploading to youtube, and gives your viewers a 720p option.
Finally, become familiar with 3rd party programs to enhance your animations. The adobe master collection is as good as anything when it comes to editing .gifs, especially after effects. This program can be used to add colour, shading, correct speed, high resolution text, lighting, you name it, to a completed animation. It is quite complex to use, but there are a wealth of tutorials online/on youtube. If nothing else, you can add simple filters to improve the pixellated feel of a .gif exported at its original size. After effects is of course not the only solution. There are hundreds of others, all a deft googling away.
Why did I write this? Of all people, I think I am the most qualified to present the perspective of an outsider, as someone who was once waist-deep in hours of painstakingly slow animation, but is now looking at the work you guys do as someone who has been out of the loop so long as to be impartial again. You are all extremely talented, and deserve far, fucking FAR more recognition, but are bottlenecked by the awful tool you limit yourselves to, and your presentation. Bigger is better.
