I spent two weeks trying out the evil mode in my daily workflow. Some things were much more user-friendly than vim but at many points the rough edges of the vim emulation on top of emacs showed its bare spots. Finally, lack of support for a good database client bought me back to spacevim which is a similar space-driven IDE written in native vim.
I find spacemacs interesting, but it feels like there's not a lot of things happening in the community. The news section on the website is old (seems from 2016?), there's no user forum, commits on github are a couple of months old. Am I missing somthing?
It seems to be actively used (150+ active pull requests, ~2000 open issues), but not actively maintained, since there is a single person behind the project, who probably took a long break from it. And to be fair, it's just a modular layer on top of Emacs, so it's not like it can get outdated any time soon.
develop branch [0] is very active and the community is quite active and plentiful in real time on Gitter [1] (it's mostly friendly and helpful, so don't be shy).
