I would imagine the source for most projects is hosted on GitHub, or similar platforms? Perhaps you could consider forks, stars, and followers as "votes" and sort each sub category based on the votes. I would imagine that would be scriptable - the script could be included in the awesome list repo, and run periodically. It would be kind of interesting to tag "releases" and see how the sort order changes over time. If you wanted to get fancy, the sorting could probably happen as part of a CI task.
If workable, the obvious benefit is you don't have to exclude anything for subjective reasons, but it's easier for readers of the list to quickly find the "most used" options.
Just an idea off the top of my head. You may have already thought about it, and/or it may be full of holes.
