There are a lot more active communities on the web. Here are a few highlights:
- An active Reddit community can be found at https://reddit.com/r/vim
- A Vim Q&A site available at https://vi.stackexchange.com/
- Neovim has a very active chat on Gitter available at https://gitter.im/neovim/neovim
- Learning resources
Everyone learns differently, and it's very hard to recommend a resource that will work for everyone. Here are a few resources I found helpful:
- Vim Tips Wiki is a huge repository of bite-sized Vim tips: https://vim.wikia.com
- Vim screencasts: http://vimcasts.org
- Learn Vimscript the Hard Way, a fantastic in-depth Vimscript tutorial: http://learnvimscriptthehardway.stevelosh.com
Bram Moolenaar, the original creator of Vim, also has a personal website with a few Vim-related notes: https://moolenaar.net. Bram is also actively involved in a non-profit making organisation helping kids in Uganda, and you can head over to his homepage to learn more about it.
Finally, I sometimes post Vim-related snippets on my blog at https://www.rosipov.com. It's usually filled with unrelated articles, but you can filter to only display Vim-related posts: https://www.rosipov.com/blog/categories/vim.
