Please, Jared, contribute to Jekyll instead. There are many contributors, and you will probably get better code reviews. Bridgetown is your one-person show where you contribute the most commits (https://github.com/bridgetownrb/bridgetown/graphs/contributo...). Who is reviewing your changes? :)
YOU can revive Jekyll :)! I would like that. No offence, but Bridgetown is probably on "hiatus" sooner or later as well. I, as a user, have no trust in these forks.
