while --it-is possible seeing how fossil confuses, for the Github conversation, it's not really in the same category, conversation, some clever happenings happening within fossil-scm, however, it's not really the same as the problem design-led github solves given people saying downtimes; sure, git, github; however how people using github, different–similar, git, however, github.
However, were you to say liken-able (slang keywords: comparative something else--) of, "fossil with git-github", then again: no.
Good call were the conversation (comments, almost interchangeable at-times haha!) being, everyone use git for Firefox, something kinda wild-topic!
